Day 31: Does Area of a Velocity-Time Graph Always Equal Displacement?
Students used motion detectors to test this out for a variety of scenarios. First they did it with a constant speed buggy to verify experimentally what we had already established during the Constant Velocity unit. Then they looked at new scenarios where the velocity was changing:
- A cart rolling down hill.
- A tissue box that speeds up (due to a push) then slows down (due to friction).
- A cart that moves across the table, hits a rubber band barrier, and returns back.
