This is a cram review of Unit 1: Kinematics for AP Physics 1 2023.
I covered the following concepts and AP-style MCQ questions.
- displacement, velocity, acceleration
- displacement vs time graph, velocity vs time graph
- slope and area of different graphs
- free-fall
- projectile motion
- center of mass, and its velocity
I need more cram review plz, ur a legend…
thank you so much for this video, i'm an undergrad university student cramming for finals and this was super helpful
I moved to the USA from India and teaching an AP Physics class. Never taught it before but this helped me to save my ass! Thank you.
Hey, I'm so glad that my videos helped. What state are you teaching at?
THANK YOU!!! i hope this isnt too much to ask but could you please add timestamps to your videos or chapters so its easier to distinguish the different topics discussed in the video? this helped me so much btw
Sure. I wanted to add timestamps but I don't know how to do it. I'll figure it out for the new videos. Thank you for your feedback
Having an exam tmr, this video saves my life (T_T)
what did u get
You are awesome, thank you so much.
Hello! Will you be covering other units like Energy, Waves and Circuits? (I am aware that you also have a Dynamics video.) I really appreciate these videos, they are incredibly helpful. Thank you!
omg please do more of these for the other units
🎯 Key points for quick navigation:
🎓 The presenter, Eugene, introduces himself as an academic coach and professional tutor, sharing educational content on kinematics for AP Physics 1.
📘 Kinematics focuses on how objects move, emphasizing displacement, velocity, and acceleration without addressing the forces behind motion.
🔄 Displacement differs from distance by considering only the starting and final positions, whereas distance accounts for the entire path traveled.
🏃 The velocity involves direction and magnitude, differing from speed, and is calculated based on displacement over time.
⏱️ Acceleration indicates how quickly velocity changes, with an emphasis on constant acceleration in the context of AP Physics 1.
📊 The analysis of motion graphs, such as velocity versus time and displacement versus time, helps understand acceleration and displacement.
🌐 Projectile motion as part of two-dimensional motion is covered, highlighting the role of gravitational acceleration and changes in velocity components.
📏 The use of kinematic equations in free-fall scenarios and other AP-style questions is explained to calculate various motion parameters.
🧮 Vertical Components: The time taken for two experiments to reach the ground is the same due to identical vertical velocity, displacement, and acceleration.
📉 Graph Analysis: A tangent line on a position vs. time graph determines the speed of a ball at ground contact, calculated to be approximately 5 meters per second.
⚖️ Center of Mass: Explains the concept of the center of mass and its calculation with multiple objects, useful for AP Physics.
🪂 Acceleration Components: Horizontal acceleration is zero, and vertical acceleration is constant (gravity), showing combined acceleration equals gravitational acceleration.
🖊️ Recording Motion: Using photogates and motion detectors accurately measures a moving object's velocity and acceleration, which must align with the object's direction.
ℹ️ Graph Interpretation: Selection of proper graph types (velocity vs. time) helps in analyzing acceleration scenarios, important for understanding constant positive acceleration.
🏹 Projectile Motion: Discusses the conditions and graph interpretation for launching an object at an angle, focusing on its vertical and horizontal components.
🎯 Dart and Target: Explains the interaction between a moving dart and a falling target, highlighting the relationship between their velocities and resulting positions.
🟰 The displacement of an object in a velocity-time graph is found by calculating the area under the curve.
📏 Questions about object displacement often involve interpreting graphs and calculating areas geometrically.
🌍 Constant acceleration in free fall is due to gravitational force, making C and D correct in certain scenarios.
🛤️ Objects on inclined paths generally experience constant acceleration, as demonstrated in example D.
🌌 The maximum height in projectile motion is influenced by initial velocity and gravitational force.
📊 In velocity-time graphs, the displacement can be zero if the areas of positive and negative regions cancel each other out.
🌀 An object spinning and moving simultaneously has non-zero displacement due to its translational motion.
📉 A decreasing velocity in a system suggests a constant acceleration, as seen in center of mass analyses.

Thank u so much for your videos. Can you make videos for AP Calculus AB like how u did for AP Chemistry.
Thank youuuu❤
legend, thanks
20:39
Hi why don't you make a video for AP Calculus AB too
Did you look at the AP chem frq 2023
1:05:20 why do we assume final velocity to be zero?
I'm not cramming, but i'm going from teaching biology to teaching AP physics lol. Thanks for these videos!!!
Thank you
❤
thank you
Guys may i ask at time 1:07:07, why did she write 2+3? upper base and lower base? height is 0.5?
The figure with green shade is a trapezoid. The upper base is 2 (vertical distance on the right side), the lower base is 3 (vertical distance on the left) and the height is 0.5 (width on the horizontal x-axis). Hope that clarifies everything :)
TYSM
Please upload more videos. Thanks
Please make more videos!!! 🙏my physics final is next week 🙏🙏🙏🙏🙏

Guys, anyone has timestamps??
u are a legend

8:45 TS
What does TS mean?
Found this video 3 days too late 😢
15:36 TS
Hi
14:33 i think youre wrong on this one
Which part? Deceleration?
@@academic-coach-youhyun no nvm i was wrong.
@@academic-coach-youhyun Can you make a video on vectors?
@@Fracasse-0x13 I’m planning for a full year course this year. Just wait for 1-2 weeks.
@@Fracasse-0x13 Let me know if you spot anything wrong
What more motivation to study than a cute girl teaching kinematics
Comment
your voice is too low you should probably raise it in future videos
Thanks for the feedback
oh, so you've never spoken to a woman in real life before, huh? surprise- not all women have naturally high pitched voices. get over yourself
wtf
@@apjoneswvwhat
@@Lily-ow5wm I'm not sure why people are critiquing her voice when it's perfectly fine. They should be grateful that someone is taking an hour out of their day to help us cram for an AP Phys 1 exam instead of doing...you know anything else
Hello thanks for the video, but why do you not include Yo initial at 25.33?
don't we also need to plug the height of the building at 25.33 as this would be the value for Y initial?
