Period and amplitude: Quantitative Observational Experiment
Devise physical variables to describe the motion of the glider on the spring and also determine whether there is a relationship between these variables.
- Potential energy
- Kinetic energy
Description of the Experiment
Observe the motion of a cart attached to a compressible spring. Decide what relevant data you can collect using the video.
400 X 300

- Draw a motion diagram for the cart for each experiment.
- Draw a free-body diagram for the cart at five different points of the cycle.
- Describe the changes of energy in the system cart-spring. Choose the same 5 points as you did in the question before.
- Why did the cart go back to the original position after it was being pulled away? Why didn't it stop when the force exereted on it by the spring was zero?
- Show the points where the cart was moving in the direction opposite to the direction of the force exerted on it by the spring. How can you explain this?
- Did it take the cart the same time to complete one full cycle in all experiments? How can you explain this?
