Pre-Lab Assignment
Conservation of Mechanical Energy
Name
1. a) As a ball is moving vertically upward from the ground, is the gravitational potential energy
(PE) increasing, decreasing, or remaining constant? (Assume the ground is the reference level.)
b) After the ball has reached maximum height and is falling, is the gravitational potential
energy increasing, decreasing, or remaining constant?
c) Write the equation for PE as a function of time
Hint: Substitute the kinematic equation for y in
one dimension into the PE equation.)
(d) Sketch a graph of the gravitational
PE (J)
potential energy vs. time for the entire
trip of the ball.
