Question

In a science lab, students determined how the mass of a cart affects its gravitational potential energy and its kinetic energy as it rolls down a ramp. One of the students held the small cart at the top of the ramp and released it to roll down the ramp. The cart’s mass is 150 g. The students ran the experiment three times. In the second round, they added a mass of 30 g to the cart. In the third round, 50 more grams were added to the weight of the cart for a total of 80 grams of mass added to the cart. The students gathered the data recorded in the table.

 

 

Describe how the gravitational potential energy and the kinetic energy of the cart change as the cart rolls down the ramp in simple terms
