Consider this equation: Kinetic Energy = mv2Which of those variables is changing as the skater moves up and down the track?
pav-90 [236]

Answer:

The changing variables are: v and KE

Explanation:

Given

KE = \frac{1}{2}mv^2

Required: What changes?

From the formula above:

KE=Kinetic\ Energy

m = Mass

v = Velocity

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
