Arrange the objects in order from least to greatest potential energy. assume that gravity is constant. (use pe = m × g × h.)

How would doubling the made of an object change the objects potential energy

Imagine that someone pushes one marble toward a motionless marble. would there still be action-reaction forces involved in the collision? how might the marbles’ motions be changed? ?

Work = force × a. work b. energy c. distance d. momentum
