Question

how does the skaters kinetic energy change as he moves down the ramp? 4 pointsincreasesdecreasesstays the sameincreases then decreaseshow does the skaters potential energy change as he moves down the ramp? 4 pointsincreasesdecreasesstays the sameincreases then decreases

Explanation:

For kinetic energy: Kinetic energy depends on speed ($KE=\frac{1}{2}mv^2$). As the skater moves down the ramp, gravity accelerates them, increasing their speed, so kinetic energy rises.
For potential energy: Gravitational potential energy depends on height ($PE=mgh$). As the skater moves down the ramp, their height above the ground decreases, so potential energy falls.

Answer:

1. Increases
2. Decreases
