It disappears
It increases
It doesn't change
It decreases
What type of energy does a stretched rubber band have?
Kinetic energy
Elastic potential energy
Mechanical energy
Thermal energy
What is elastic potential energy dependent on?
Color of object
Weight of the object
Shape and material of the object
Size of object
The energy of a bow changes when the string is pulled back.
Elastic potential energy will decrease.
Elastic potential energy will increase.
Gravitational potential energy will decrease.
Gravitational potential energy will increase.
A student makes a slingshot to launch a bean across a room, as shown.
What will likely occur if the student replaces the rubber band with a shorter rubber band, and why?
The bean will travel a larger distance because the piece of cloth is better attached to the wooden support with the shorter rubber band.
The bean will travel a larger distance because the shorter rubber band creates more elastic potential energy.
The bean will travel a smaller distance because the shorter rubber band stores less elastic potential energy.
The bean will travel a smaller distance because the weights of the bean and the shorter rubber band are similar.
At which point does the cart have the most potential energy?
W
X
Y
Z
Which scenario shows a decrease in gravitational potential energy?
an airplane taking off from a runway into the sky
a leaf on a tree falling to the ground
a car accelerating on a highway
a log burning in a fireplace
The image shows three skiers at the top of three hills of different heights.
Which statement correctly describes the skiers?
All three skiers have different amounts of elastic potential energy.
All three skiers have different amounts of gravitational potential energy.
Skier 1 has elastic potential energy, and skiers 2 and 3 have gravitational potential energy.
Skier 1 has gravitational potential energy and skiers 2 and 3 have elastic potential energy.
