Question

How does the potential and kinetic energy change as the sled moves down the slope?

Answer 1

KE increases and PE decreases.

Step-by-step explanation:

First, note that the formula for kinetic energy is KE = (1/2)mv^2 where m is the mass and v is the velocity and the formula for potential energy is PE = mgh where h is the height it is at. Since mass and the acceleration provided by gravity doesn’t change, we can disclude that our conclusion. We know that the height (h) and velocity (v) does change, so let’s look at that. As you continue down the slope, you accelerate due to gravity. Thus, velocity increases and KE increases. As you continue down the slope, you get closer to the ground, hence h decreases and PE decreases.

I hope this helped! :)
