Unit 3: Energy Final Exam REVIEW

Front

What does temperature measure in a material?

Back

Temperature measures the average kinetic energy of the particles in a material.

Front

What happens to the kinetic energy of an object as its speed increases?

Back

The kinetic energy of an object increases as its speed increases.

Front

Which pictures show the same type of thermal energy transfer?

Back

Pictures A and C show the same type of thermal energy transfer.

Front

If two trucks have the same velocity but different masses, which truck has more kinetic energy?

Back

The truck with the greater mass has more kinetic energy.

Front

What is an example of energy conversion from kinetic to thermal energy?

Back

Friction is an example of energy conversion from kinetic to thermal energy.

Front

Define kinetic energy.

Back

Kinetic energy is the energy an object possesses due to its motion.

Front

What is the formula for calculating kinetic energy?

Back

Kinetic energy (KE) = 1/2 mv², where m is mass and v is velocity.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance.

Front

How does mass affect kinetic energy?

Back

Kinetic energy increases with mass if velocity remains constant.

Front

What is the relationship between temperature and kinetic energy?

Back

As temperature increases, the average kinetic energy of particles increases.
