Energy Test 24/25

Front

When there is friction between surfaces, energy is transferred out of the system as _____________ energy.

Back

Thermal energy is the energy transferred due to friction, resulting in heat.

Front

What type of energy does an object have when it is pulled back in a slingshot before being released?

Back

Elastic potential energy is stored in the slingshot when it is pulled back.

Front

What change could be made to a roller coaster to ensure it works?

Back

Make the starting hill taller than the other hills to provide enough potential energy.

Front

What type of energy is released from food after it is eaten?

Back

Chemical energy is released from food during digestion.

Front

What causes a ball to stop when rolled across the floor?

Back

Friction is the force that causes the ball to eventually stop.

Front

Define kinetic energy.

Back

Kinetic energy is the energy of an object in motion, dependent on its mass and speed.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its height above the ground.

Front

Explain the law of conservation of energy.

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is the difference between potential energy and kinetic energy?

Back

Potential energy is stored energy based on position, while kinetic energy is energy of motion.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, often converting kinetic energy into thermal energy.
