Answer:
The changing variables are: v and KE
Explanation:
Given
Required: What changes?
From the formula above:
m: The mass of the skater is constant.
v: Moving up and down the track may change the velocity of the skater.
KE: When velocity changes, the kinetic energy also changes
So:
The changing variables are: v and KE
