As the cars of a roller coaster are pulled up the incline to their starting position, they are gaining potential energy. (3 points)
• True
• False
The closer the cars of a roller coaster get to their starting point, the less potential energy they have. (3 points)
• True
• False
The energy of motion is known as: (3 points)
Newton's energy
potential energy
kinetic energy
stored energy

Match the following terms with the correct definition. (4 points)
kinetic energy
mass
law of conservation of energy
speed
energy
potential energy
:: the ability to do work; how objects change or move : the energy of motion
:: a measure of the amount of matter in an object
: distance traveled per unit of time, how fast an object is moving
* energy is transferred from one type to another; energy cannot be created nor destroyed
: stored energy that depends on an object's position relative to the earth.

Answer 1

1) Potential Energy is: stored energy.

2) As the cars of a roller coaster are pulled up the incline to their starting position, they are gaining potential energy.
- True

3) The closer the cars of a roller coaster get to their starting point, the less potential energy they have.
- False

4) The energy of motion is known as:
- kinetic energy

Match the terms to definitions:
- energy → the ability to do work; how objects change or move
- kinetic energy → the energy of motion
- mass → a measure of the amount of matter in an object
- speed → distance traveled per unit of time, how fast an object is moving
- law of conservation of energy → energy is transferred from one type to another; energy cannot be created nor destroyed
- potential energy → stored energy that depends on an object's position relative to the earth
