4. Complete each sentence by highlighting the correct word in parentheses.
a. If two objects of different masses are about to be dropped from the
same height, the heavier one has (GREATER / LESS / EQUAL
AMOUNTS) gravitational potential energy.
I
b. If two marbles are rolled down a ramp from the same height toward a
container, the (LIGHTER / HEAVIER) marble will move the container
more because it has more (POTENTIAL / KINETIC) energy as it reaches
the bottom.
c. If one water balloon is held 1 meter above the ground and another
water balloon the same size is held 3 meters above the ground, the
(HIGHER / LOWER) water balloon has the greater amount of
gravitational potential energy.
d. When balloons are dropped, the (HIGHER / LOWER) balloon will hit the
ground with more force because it will have (MORE / LESS) kinetic
energy.
