Mechanical Advantage in Z-Drag System
มุมมอง 8411 หลายเดือนก่อน
If you wonder how the physics you are learning at high school applies to everyday life, this video is for you. You will learn how two basic principles of (a) mechanical advantage and (b) the conservation of energy can help design a Z-drag system that can do many things, for example, help you rescue a canoe. Next time you solve a multiple-pulley problem, or enjoy nature on the nearby rapids, thi...
Searching for Exoplanets: The Transit Method
มุมมอง 6811 หลายเดือนก่อน
Do you know how scientists discover exoplanets? These are the planets that are located outside of our Solar System. This video will show you how it can be done and how the physics you are learning in your classroom can help you understand the ideas behind the Transit Method used in astronomy.
Painting Damped Oscillations with a Simple Pendulum
มุมมอง 8411 หลายเดือนก่อน
Have you ever wondered how the motion of a pendulum translates to a graph? In this video, we use a simple pendulum demonstration to paint the motion of a damped oscillation. By deriving the equation of motion and considering friction applied on the pendulum system, we learn that the resulting graph is a sinusoidal graph with decreasing amplitude - a damped oscillation! Resources used in this vi...
Exploring sound waves: Resonance with pipes
มุมมอง 11111 หลายเดือนก่อน
Are you curious about how wind instruments make their sound? Or sometimes you just hear an airy sound? Well, this is all due to a phenomenon called resonance! But what is resonance? How can we tell if something is in resonance? In this video, we will learn what resonance is, how sound is created inside palm pipes, how air particles move inside a tube when it is in resonance and finish off by bl...
The Physics of Pythagoras Cup
มุมมอง 13011 หลายเดือนก่อน
Maybe you have heard about the concept of a syphon (siphon) and most certainly you have used it, but what is the physics behind the syphon? We will explain it using a famous physics demonstration called Pythagoras cup. We will also show what happens when instead of water you use a denser fluid.
Physics of Resonance: From tuning forks to playground to MRI
มุมมอง 29511 หลายเดือนก่อน
Have you every thought how the physics of resonance you are learning in your classrooms is applicable to your everyday life? What are resonance frequencies and how do we find them? Can we see how the energy can be transferred from one tuning fork to the other one through sound waves? This video will help you answer these questions using an example of two resonating tuning forks. You will see a ...
Waves and Energy Transfer

Analyzing the Effect of Radius on Angular Acceleration of Rolling Sprockets Down a Ramp
มุมมอง 54ปีที่แล้ว
To investigate the connections between dynamics and rotational motion, various sizes of sprockets were rolled down a fixed-slope linear ramp, and by measuring the auditory clicks of the sprockets down the ramp, the angular velocity, and hence the angular acceleration, were measured from each trial. From 7 trials of 3 differently-sized ramps, it was found that the hypothesis that the angular acc...
Investigating circular motion with Phyphox
มุมมอง 76ปีที่แล้ว
In this video, the students designed a very creative apparatus to investigate circular motion with the help of the Phyphox app. This experiment can be performed in a lab or at home and will fit perfectly with the secondary physics curriculum.
Exploring sound through investigating echoes with Phyphox
มุมมอง 72ปีที่แล้ว
In this experiment, the students are using Phyphox to understand the echo phenomenon in sound waves. While many of us have experienced it, not many have done any measurements when experiencing it. These experiments can be conducted at home or during a physics lab and the students will only need their smartphones with the Phyphox app in them.
Energy conservation in a pendulum
มุมมอง 65ปีที่แล้ว
In this experiment, the students built a pendulum to investigate mechanical energy transformations. Specifically, they use a Phyphox app and the Doppler effect to measure the speed of the pendulum at its lowest location to evaluate the kinetic energy of the pendulum.
Exploring standing waves and harmonics using PhET and Audacity applications
มุมมอง 148ปีที่แล้ว
Many secondary students learn to play musical instrument, but few students understand the physics behind the sound and sound waves. In this lab, the students show how students can do that using PhET computer simulations, Audacity application and a violin.
Exploring electromagnetism: A homemade railgun experiment
มุมมอง 933ปีที่แล้ว
In this experiment, the students built a rail gun in order to explore the magnetic force acting on a current carrying wire. This experiment can demonstrate the Lorenz force, and also show how one can make relevant measurement and do a physics lab with this but creative yet simple apparatus. The acceleration of a rail gun projectile was investigated both qualitatively and quantitatively.
Exploring magnetic field of an electromagnet with Phyphox
มุมมอง 586ปีที่แล้ว
Students built an electromagnet using materials available either in a physics lab or even at home. Then they examined its electric field using Phyphox app. It is an excellent lab to use in a physics class or during an independent investigations by the secondary school students.

    There is a contradiction in your definition of stable equilibrium and your example at 2:20 . In the example , the centre of mass of that figure on a motorbike is ABOVE the point of support (ie. the wire). Yet your definition says 'stable equilibrium' when the COM is BELOW and in line with the resting point , or point of support.

    Hey thanks for this video, I have taken inspiration from this experiment you have done and did it myself for my IB physics IA (essay). I'm confident my essay will get good grades as I delved into most of the things in depth and that's mainly from the experiment you did. Simple but effective!

    I'm confused, I had one my cat broke it. It smelt so strong, like chemicals. My daughter walked over to it and got some on her before I could stop her. I took her to the hospital because I didn't know what was in it, or if she got some in her mouth. She was okay, praise the Lord. A lot of people say it has ethanol in it, even the website states it. This smells like straight up motor fluid! Its so strong, I had to throw away a whole basket of clothes because the liquid spilled on them. I am wondering if the older models have something else in them? I got mine for free, it was maybe 30 1:00 years old?

    With the rising temperature of the liquid also the liquid in the balls rises. Does the density of the balls change as well?

    • @sciencematheducationvideos2300
      @sciencematheducationvideos2300 ปีที่แล้ว

      Good question. The density of the balls doesn't change, as the glass doesn't expand much under these conditions. So the volume of the balls stays unchanged and its mass as well, so the density of the balls doesn't change in this temperature range. Good question!

      I am not sure how it would be related to the climate when the thermometer is sealed. I do not think one has to calibrate it to the climate and the temperature measurement is universal.

    The reason your lens fog up is the warm moist air full of germs (both bacterial and viral) are escaping through the gap at the bridge of your nose. The moisture condenses on the lens, fogging it up as the germs are forced higher into the air to spread farther through the gap at the bridge of the nose.
