Question

Consider this equation: Kinetic Energy = mv2Which of those variables is changing as the skater moves up and down the track?

Answer 1

The changing variables are: v and KE

Step-by-step explanation:

Given

`KE = (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
