Lab 12: Energy Conversions
Purpose
To measure the conversion of energy between potential and kinetic using an
inclined plane
Background
Knowing how energy behaves is even more important than knowing what it is.
The law of energy conservation states that energy cannot be either created or
destroyed. So the energy of a system must remain the same before and after
things happen to it. A person walking to the top of a burning building has to
work to climb the stairs. The energy from the work is then stored in potential
form because of the force of gravity pulling her down. If she were to jump from
the burning building onto a fire fighters’ trampoline, her potential energy
would be converted into kinetic energy as she was falling. As she speeds up
while falling, her potential energy decreases because she is closer to the ground
and her kinetic energy increases as her speed increases. When she hits the
trampoline she will slow down and her energy will convert into vibrations
(elastic potential energy), heat and noise.
Skills Focus
Making generalizations, interpreting data, applying concepts, drawing
conclusions
Procedure
1. Start Virtual Physics and select Energy Conversions from the list of
assignments. The lab will open in the Mechanics laboratory.
2. The laboratory will be set up with a ramp, a ball on the ramp, and a plunger
on the ball. Using the Force button to hit the plunger, you will push the ball
up the ramp. The ball will stop at some point and come rolling back down
the ramp.
3. You will need to record and use the data from the experiment. Click on the
Lab Book to open it. The click the red Recording button. When the Force button
is clicked, the data selected with the check marks will be automatically
recorded.

4. Click the Force button to hit the ball up the ramp. Then watch the ball fall
back to the bottom.
