Write 5 facts that you ALREADY
know about ENERGY
The ability to do work or to cause change or movement in matter

Work is done when a force moves an object through a distance
Potential Energy 1. Is stored energy
2. Depends on an object’s mass and position
A. The larger an object’s
mass, the greater its PE
B. The higher up an object is, the greater its PE

More Examples of Potential Energy
1. Is energy in motion
2. KE depends on an objects mass and its speed.
Kinetic Energy
3. KE also depends
on the amount
of stored energy
(PE) the object
has.

More Examples of Kinetic
Energy
Potential energy
is transformed
into kinetic
energy as you
move
How are kinetic and potential energy related?

RULE:
The more potential
energy an object has
the more kinetic
energy it will have
when moving.
LAW:
Energy is never
created or
destroyed, only
transformed.
Bear vs. Ball Lab 1. Work in groups to
demonstrate and
measure potential
and kinetic energy!
2. Only use baby
bear in your actual
experiment!

Bear vs. Ball Lab Setup 1. Place your ring stand on the
floor
2. Mark a dot on the floor at the
center of the ball
3. Draw two lines to mark
where to place your bear
4. Fully extend your ball
backwards and make
another dot
5. Always line up your shot
along this line
Ball
6. Place the ruler behind the
ball so you can measure
your height
