Kinetic and Potential Energy WRA

What is kinetic energy?

• The energy stored in an object due to its position.

• The energy of motion.

• The energy an object has because of its mass.

• The energy transferred between objects.

What two factors determine the amount of kinetic energy an object has?

• Its speed and shape.

• Its mass and position.

• Its speed and mass.

• Its size and volume.

What is an example of potential energy given in the passage?

• A car driving down the highway.

• A rock perched at the edge of a cliff.

• A fast-moving baseball.

• A bicycle going at the same speed as a car.

How is potential energy converted into kinetic energy in a roller coaster, according to the passage?

• By increasing the speed of the coaster as it climbs a hill.

• By the coaster gaining speed as it descends a hill.

• By the coaster slowing down at the top of a hill.

• By the coaster stopping at the bottom of a hill.

What principle states that energy cannot be created or destroyed, only converted from one form to another?

• The law of kinetic energy.

• The law of potential energy.

• The conservation of energy.

• The principle of energy transformation.
