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
