As a roller coaster travels up a hill, its potential energy is doing this.
What is increasing?
100
Scientists classify all energy into these two kinds of energy.
What are potential and kinetic energy?
100
A moving roller coaster at the bottom of a hill.
What is kinetic energy?
100
When a bicycle is coasting on a level sidewalk, it has this type of energy.
What is kinetic energy.
200
The location where a roller coaster has the most kinetic energy.
Where is the bottom of the hill?
200
Stored energy, or energy that an object has due to its position.
What is potential energy?
200
A new package of batteries.
What is potential energy?
200
A roller coaster car has the most potential energy and least kinetic energy when it is in this location.
What is at the top of the hill?
300
As the speed of the roller coaster decreases, the kinetic energy does this.
What is decreases?
300
The energy of motion.
What is kinetic energy?
300
The food we eat.
What is potential energy?
300
As a roller coaster car goes downhill, it has used up half the potential energy it had at the top when it reaches this point.
What is halfway down the hill?
400
The two forces that acted on the marble as it was traveling on the "roller coaster" in our investigate activity.
What were gravity and friction?
400
In our investigate activity involving the ruler and cup, the higher ramp allowed the marble to pick up more of this, thus giving it greater kinetic energy at the bottom of the ramp.
What is speed?
400
Holding a wound rubber band that propels a toy airplane.
What is potential energy?
400
Of a 20 meter hill and a 10 meter hill, the one on which roller coaster cars will have the greater kinetic energy at the bottom.
