Draw/ Answer the following Problem A man throws a 1 kg ball up in the air with an initial velocity of 10 m/s. 1) What type of energy was the ball thrown up in the air with? Calculate it 2) At the very top of the ball’s path, what type of energy does the ball have?

Create your own Energy Map for the following scenario Create your own Energy Map for the following scenario. (Make sure to calculate the energy if you can .) A ball is dropped off a cliff from rest. After 10 seconds the ball hits the water. You can hear the splash .

Is the ball’s kinetic energy the same at the beginning and at the end? If we throw the ball up with an initial velocity of 10 m/s, what is the velocity of the ball when it is falling back down? Is the ball’s kinetic energy the same at the beginning and at the end? What is the KE? Mass = 1 kg Vi=10m/s Vf=?
