Title1D60.10 - Relativity Cart
Objective

Demonstrate that an object thrown upward while moving horizontally at a constant velocity will follow a parabolic projectile curve and land back in the cart.

StatusAvailable
Assembly Instructions

The relativity cart is a cart with a spring launcher that (when calibrated) launches the ball directly upwards.
Place the track on the table and level. Put the tunnel on the track right beside the photogate trigger. Adjust the photogate trigger so it will trigger the cart. Place the cart on the track and launch the ball. The ball launches when the photogate is triggered, so pass the cart is on, the launcher is set (by pressing on it) and the photogate is triggered.
Level the launcher depending on where the ball lands. The ball should land directly in or near the launcher.
Once the ball is calibrated, test the process while pushing the cart. If it catches the ball 4/5 times then it is well calibrated.

Operation Instructions

 

1   Turn on the cart, and prime the ball by pressing it into the cart until the spring catches.

3   Re-prime the cart by pressing the ball into the launcher.
4   This time push the cart so that it is travelling when the ball launches.
5   The ball will land in the cart even though the cart was travelling when it launched the ball.
