NG088004

When a student shoots a rubber band across the room, the elastic energy of the rubber band is transformed into motion energy, and the total amount of energy stays the same. (This item uses bar graphs to depict the amount of each kind of energy.)

NG049004

When a spring is used to shoot a cart across the floor, the spring transfers energy to the cart. (This item uses bar graphs to illustrate the amount of elastic energy the spring has and the amount of motion energy the cart has as the cart is rolling across the floor.)

NG078003

After a rubber band is used to shoot a toy car across the floor, the total energy of the system will remain the same because the increase in the motion energy (kinetic energy) of the car is the same as the decrease in the elastic energy of the rubber band.

NG007004

When you let go of a stretched rubber band, the elastic energy that the rubber band has when it is stretched is converted into motion energy.

NG051002

When a rubber band is used to shoot a toy car across the floor, the rubber band has less energy because energy was transferred to the car.

For two identical springs, the spring that is compressed more has more elastic energy.

EG041004

For two identical rubber bands, the rubber band that is stretched more has more elastic energy.

RG052003

The more a rubber band is stretched the more energy it has.

NG012003

When a ball bounces off a floor, the elastic energy of the ball is converted into motion energy and gravitational potential energy.

RG054003

A spring has more energy if it is compressed more.

8%

RG051003

A rubber band that is stretched more will travel farther when let go than a rubber band that is stretched less because the more a rubber band is stretched the farther it will travel.

7%

RG053003

A spring will jump higher if it is compressed more before letting go.
