Potential Energy Quiz Review
2
Which slide provides the most gravitational potential energy?
The blue one of course because of it's height!
3
How does the gravitational potential energy of the first hill compare to the second hill?
Probably close to double the amount of Graviational PE in the first hill compared to the second due to it being almost twice as tall.
4
Use this formula to calculate the following:
What is the KE of a 100 Kg go-kart travelling at a speed of 2 m/s?
Solve then go to the next slide for the answer.
