Lab #9.7
Mechanics: Chapter 9
Dropping The Ball
Purpose
In this experiment, you will
lift a ball and drop it. You
will determine and compare the
potential energy of the ball
before it’s dropped to the
kinetic energy of the ball after
right before it hits the ground.
Discussion
When an object is lifted, the
work done to lift the object is
transformed into potential
energy. If the object is then
dropped, the potential energy is
transformed to kinetic energy as
it falls. In this experiment, we
will determine the potential
energy of a lifted object. We
will also determine the kinetic
energy of a dropped object. We
will then compare the potential
energy that an object has when
it is lifted to a certain height
to the kinetic energy it has
after it has fallen from that
height.

A sponge can be
used for noise suppression if
desired. Any common household
sponge would work. |
