- NET FORCE Video Series - This EXTRA PRACTICE video shows how to solve a newton's second law problem where we solve for net force and acceleration. The force is applied at an angle, so it is necessary to break the applied force down into its x and y values. This is an awesome video if you need extra practice or examples solving net force problems.

This is exactly what I was looking for! I'm glad I found your channel, keep up the good work!
What you have learned my in 11 minutes, took my teacher 11 lessons to explain.
MrFIFAGamer This video was easy for you to understand because of those 11 lessons.
i love that you follow up your answers with "BECAUSE"... you explain how you got there, which is delightful
Wonderful, very clear explanation. Thank you for a very informative video on this topic!
Thank you thank you so muchhh you saved me from failing my physics exam
Fnetx = 27.7 N just a little minor mistake :D thank you for the video!
thankyou my friend. your video explanation was superb. For a beginner is a fantastic explanation. like to see more of your videos on forces.
i wish you were my physics teacher
Shawn Heaton Physics is a great class to teach. Keep tuning back in. Unfortunately, I don't have an abundant amount of videos. Best wishes in learning!
thanks
you're the best!!!
Helpful video.
Thanks a lot
Isn't normal force equal to Fg? And how this will be different if he was pushing with same force at same angle from the other side of the object?
ali abrahimi Consider that pushing down and pulling up will change the normal force and therefore the force of friction. If you pull up, the normal force is reduced and there is less friction to overcome. If you push down, then Fg and Fapp-down add together downward, therefore the force normal must equal that in the opposite upwards direction. This is if there is no acceleration up or down, hence balanced forces. Pushing down will make a greater normal force and therefore increase friction. The Fnet will be less and so will the acceleration. Hope it helps.
sciencepost And...excellent question!
sciencepost Asked this because I mentioned this to my professor when he was solving a similar example. He did not take the y-direction of F into consideration. while calculating friction. When I asked him he said we should ignore the y component.
ali abrahimi Negative on that. Just think about it....When you push down on something to try to move it, it requires more of an effort in the x direction than if you pulled up....why??? It's the friction resulting from the increased normal force. Keep in mind that if there is no acceleration up or down, then the forces must cancel/balance. When you wrap your brain around it, it should make sense.
sciencepost Fn and Fg are the same, then they should be cancel out.
How to find the angle before the object start to slip down??? Given co efficient of friction,mass.
Hey, I thought the net force is just like the sum vector of all forces in the x-direction and Y-direction... You only computed the net force on the x-component and disregarded the y-component w/c is 11 N. I calculated it with the y-component.
Fnet= sqrt(Fn^2+Fx^2) w/c equals to 29.84 N, that's my net force and my acceleration is..
a=F/m w/c equals to 9.95 m/s^2.
Am I doing it right? Thanks :)
Physics (F=ma) test: “Without”applying the Energy from within you, choose an object of your choice, and apply only the Force or Net Force needed to push it away from you or pull it towards you. Please let me know if you’re able to. This is only a test. Thank you.
+sciencepost while finding the force of friction you're supposed to take the normal as all the +y components when the object is at rest!
Something very similar to this was on the 2023 FE
ok so from 38N you must magically get more total force when combining horizontal and vertical forces, where does that force come from
terribly worded question. When you say apply a force on object, it is unclear if he is pushing or pulling. In this case he is pulling the object.
Exactly what I was thinking. I solved it with the force being a push.
How would you push it at an angle of 29 degrees? That pretty much implies he's pulling it, but don't worry, he explains one minute and five seconds later.
So would i have to use the pythagorean thereom to find the fapp or is the fapp 33.2N?
I have a test tomorrow and im sooo crammming
is Fg really is negative? is there a negative force??
Thanks alot fam !!!!
So glad!
thanks for the video. I couldnt understand why on the Net Force on X direction you.just added F friction and F x . why you didnt add the force of gravity like you did on the y direction. please help me I have an exam coming up. thanks in advance
Moscow Aviation Institute - MAI - International Student's Page has given the following the thumbs up. It's all clearly correct.
The Institute of Physics, Patna has now given the following writing the thumbs up. Excellent.♥️
THE MATHEMATICAL PROOF THAT ELECTROMAGNETISM/ENERGY IS GRAVITY IN A BALANCED FASHION IS SUCCESSFULLY DEMONSTRATED:
"Mass"/ENERGY IS GRAVITY. ELECTROMAGNETISM/ENERGY IS GRAVITY. THE SUN AND THE EARTH are F=ma AND E=mc2, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. E=mc2 is DIRECTLY AND FUNDAMENTALLY DERIVED FROM F=ma. F=ma AND E=mc2 PROVE that ELECTROMAGNETISM/ENERGY IS GRAVITY, AS ALL of SPACE is NECESSARILY ELECTROMAGNETIC/GRAVITATIONAL (IN BALANCE); AS ELECTROMAGNETISM/ENERGY IS GRAVITY. "Mass"/ENERGY IS GRAVITY. ELECTROMAGNETISM/ENERGY IS GRAVITY. Energy has/involves GRAVITY, AND ENERGY has/involves inertia/INERTIAL RESISTANCE. Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. This explains F=ma AND E=mc2, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. SO, GRAVITATIONAL FORCE/ENERGY IS proportional to (or BALANCED with/as) inertia/INERTIAL RESISTANCE; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. ACCORDINGLY, ALL of SPACE is NECESSARILY ELECTROMAGNETIC/GRAVITATIONAL (IN BALANCE); AS ELECTROMAGNETISM/ENERGY IS GRAVITY. "Mass"/ENERGY involves BALANCED inertia/INERTIAL RESISTANCE consistent WITH/AS what is BALANCED ELECTROMAGNETIC/GRAVITATIONAL FORCE/ENERGY, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. GREAT !!! Gravity IS ELECTROMAGNETISM/ENERGY. ELECTROMAGNETISM/ENERGY IS GRAVITY. INDEED, A PHOTON may be placed at the center of THE SUN (as A POINT, of course); as the reduction of SPACE is offset by (or BALANCED with) the SPEED OF LIGHT; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. GREAT. "Mass"/ENERGY IS GRAVITY. ELECTROMAGNETISM/ENERGY IS GRAVITY. ALL of SPACE is NECESSARILY ELECTROMAGNETIC/GRAVITATIONAL (IN BALANCE), AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Great. The ability of thought to DESCRIBE OR RECONFIGURE sensory experience is ULTIMATELY dependent upon the extent to which THOUGHT IS SIMILAR TO sensory experience. (THOUGHTS ARE INVISIBLE.) Gravity IS ELECTROMAGNETISM/ENERGY. ELECTROMAGNETISM/ENERGY IS GRAVITY.
Very importantly, outer "space" involves full inertia; AND it is FULLY INVISIBLE AND black. The perpetual motion of WHAT IS THE EARTH is NOW explained. GREAT !!! The idea that THE PLANETS are "falling" in what is "curved space" in RELATION to what is THE SUN is PROVEN to be NONSENSE. So, the falling objects must be considered in RELATION to WHAT IS THEN THE ORBITING EARTH. GREAT !!!!!!!!!!

THE ULTIMATE (AND CLEAR) MATHEMATICAL UNIFICATION (AND PROOF) REGARDING PHYSICS/PHYSICAL EXPERIENCE IS NOW DEMONSTRATED, AS E=MC2 IS F=MA: TIME DILATION ultimately proves (ON BALANCE) that E=mc2 IS F=ma, as ELECTROMAGNETISM/energy is gravity. This NECESSARILY represents, INVOLVES, AND DESCRIBES what is possible/potential AND actual IN BALANCE. (Importantly, balance and completeness go hand in hand.) The stars AND PLANETS are POINTS in the night sky. NOW, A PHOTON may be placed at the center of WHAT IS THE SUN (as A POINT, of course); AS the reduction of SPACE is offset by (or BALANCED with) the speed of light (c); AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Indeed, ultimately and truly, TIME is NECESSARILY possible/potential AND actual IN BALANCE; AS E=MC2 IS F=MA; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Very importantly, outer "space" involves full inertia; AND it is fully invisible AND black. GREAT. Accordingly, INSTANTANEITY is thus FUNDAMENTAL to what is the FULL and proper UNDERSTANDING of physics/PHYSICAL EXPERIENCE; AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/energy is gravity. It ALL CLEARLY makes perfect sense. Gravity IS ELECTROMAGNETISM/energy. E=mc2 IS F=ma. ELECTROMAGNETISM/ENERGY IS GRAVITY. E=MC2 IS F=MA. GREAT !!! Gravity AND ELECTROMAGNETISM/energy are linked AND BALANCED opposites, AS E=mc2 is F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Consider THE MAN who is standing on what is THE EARTH/GROUND. Touch AND feeling BLEND, AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. The stars AND PLANETS are POINTS in the night sky. GRAVITATIONAL force/ENERGY IS proportional to (or BALANCED with/as) inertia/INERTIAL RESISTANCE, AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Accordingly, the rotation of WHAT IS THE MOON matches it's revolution. Great. MOREOVER, a given PLANET (including what is THE EARTH) then sweeps out equal areas in equal times consistent WITH/AS F=ma, E=mc2, AND what is perpetual motion; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/energy. INSTANTANEITY is thus FUNDAMENTAL to what is the FULL and proper UNDERSTANDING of physics/physical experience, AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. This NECESSARILY represents, INVOLVES, AND DESCRIBES what is possible/potential AND actual IN BALANCE. Stellar clustering ALSO proves ON BALANCE that E=mc2 IS F=ma, AS ELECTROMAGNETISM/energy is gravity. Objects (including WHAT IS the falling MAN) fall at the SAME RATE (neglecting air resistance, of course), as E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. "Mass"/energy is gravity. ELECTROMAGNETISM/ENERGY IS GRAVITY. E=mc2 IS F=ma. THE DOME of a PERSON'S EYE is ALSO VISIBLE. (Notice the flat AND black space of what is THE EYE.) The stars AND PLANETS are POINTS in the night sky. The sky is blue, AND the Earth is blue. THE EARTH/ground AND THE SUN are E=mc2 AND F=ma IN BALANCE, AS ELECTROMAGNETISM/ENERGY IS UNIVERSALLY PROVEN TO BE GRAVITY in what is a mathematically unified fashion. E=mc2 IS F=ma. The middle distance in/of/AS SPACE AND the full distance in/of/AS SPACE are NECESSARILY linked AND balanced. MAGNIFICENT !!!!!!!!!! INSTANTANEITY IS thus FUNDAMENTAL to what is the FULL and proper UNDERSTANDING of physics/physical experience, AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/energy. It is ALL CLEARLY proven. Again, the stars AND PLANETS are POINTS in the night sky. GREAT. Energy has/involves GRAVITY, AND ENERGY has/involves inertia/INERTIAL RESISTANCE. GRAVITATIONAL force/ENERGY IS proportional to (or BALANCED with/as) inertia/INERTIAL RESISTANCE, AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. It is all CLEARLY proven !!!!!!!! TIME is NECESSARILY possible/potential AND actual IN BALANCE, AS E=MC2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/energy. GREAT !!!!!!!! BALANCE and completeness go hand in hand. By Frank DiMeglio
THANK YOU!!!!
Where is he applying the force from?
2+2=4-1=3 quick math.
🔥(mans no hot)🔥
may I know why your Fg has a -ve for gravity ?
gravity pushes down. Normal force is up.
really helpful so i will drop a like and a subscription.
Thanks for the feedback. It's always sweet to hear. Best wishes in your studies...be awesome!
Cos29’ x 38 = -28.45
29 deg not radians..
why is this type of question so hard to find
Post ma nigga
HOW DO YOU DO IT WITHOUT THE DEGREE WHY IS EVER TH-cam VIDEO I LOOK UP TO HELP ME COMPLETE CRAP
without the angle you literally can't solve?
