This quiz involves questions related to the kinetic and potential energies of different objects. The students will be required to find out if the potential energy of an object is increased or decreased after a particular event, they also need to compare the kinetic energies of two objects.
Read the text about an object in motion.
Elena was walking with a helium balloon when the balloon's string slipped out of her hand. The balloon floated toward the sky.
Complete the statement. Assume that the balloon's mass did not change.
As the balloon floated towards the sky, the gravitational potential energy between the balloon and Earth ##increased##.

Manuel and Tristan were playing air hockey on a level table. When Manuel hit the hockey puck, it slid quickly toward Tristan's goal.
Complete the statement. Assume that the hockey puck's mass did not change.
The gravitational potential energy between the hockey puck and Earth ##stayed the same## as the puck slid toward the goal.
