Question

1. students used this setup to investigate the connection between kinetic energy and speed.

the students rolled the ball down the ramp from different heights. the cup at the bottom of the ramp caught the ball, and it moved a distance depending upon the ball’s speed. after each trial, the students calculated the ball’s speed and measured the distance the cup moved. the graph shows the students’ results.
distance the cup slides vs. speed
describe the relationship between kinetic energy and the speed of the ball. be sure to use evidence from the investigation to support your answer.

Explanation:

The relationship between kinetic energy and the speed of the ball is that as the speed of the ball increases, its kinetic energy also increases. Evidence from the investigation: The graph "Distance the Cup Slides vs. Speed" shows a positive linear trend. When the ball's speed increases (as calculated after each trial), the distance the cup moves also increases. Since the cup's movement distance is dependent on the ball's kinetic energy (more kinetic energy means more work done on the cup, moving it farther), the increasing distance with increasing speed indicates that kinetic energy increases with speed.

Answer:

As the speed of the ball increases, its kinetic energy increases. Evidence: The graph shows a positive linear relationship between the distance the cup slides (dependent on the ball’s kinetic energy) and the ball’s speed, so as speed increases, the distance (and thus kinetic energy) increases.
