This lab examines the relationship between the drop height (gravitational potential energy) and the height that the ball bounces back up.
Student teams of 2 work to calculate the GPE (gravitational potential energy of drops from different heights.
Students identify variables, make a hypothesis, fill in a data table, and create a graph to analyse the patterns they see.
Background Information: Energy cannot be created or destroyed. Stored energy is called potential energy, and the energy of motion is called kinetic energy. Due to gravity, potential energy changes as the height of an object changes, this is called gravitational potential energy.
Driving Question: “Does the drop height of a tennis ball affect the bounce height the ball?”
