Answer:
The changing variables are: v and KE
Explanation:
Given
[tex]KE = \frac{1}{2}mv^2[/tex]
Required: What changes?
From the formula above:
[tex]KE=Kinetic\ Energy[/tex]
[tex]m = Mass[/tex]
[tex]v = Velocity[/tex]
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
