Energy and Heat Transfer Pre-Assessment

Front

What increases an object's thermal energy?

Back

Increasing the kinetic energy of the particles in an object.

Front

What type of energy does a stretched rubber band contain?

Back

Elastic potential energy.

Front

When does a car have the most kinetic energy?

Back

When the car's speed is 30 miles per hour.

Front

How does the Sun transfer energy to Earth?

Back

By electromagnetic waves.

Front

What happens to energy when a rock falls from a cliff?

Back

Potential energy is transformed into kinetic energy as the rock falls.

Front

Define thermal energy.

Back

The total kinetic energy of all the particles in an object.

Front

What is kinetic energy?

Back

The energy an object has due to its motion.

Front

What is potential energy?

Back

The energy stored in an object due to its position or state.

Front

What is elastic potential energy?

Back

The energy stored in an object when it is stretched or compressed.

Front

What is the relationship between kinetic energy and speed?

Back

Kinetic energy increases with the square of the speed of an object.
