Interactions Unit 2 Part 1 Exam Review

Front

What happens to the cars' electric potential energy when they start to move after the wedges are removed?

Back

The cars' electric potential energy converts into kinetic energy.

Front

What is the relationship between kinetic energy and gravitational potential energy when a basketball is dropped?

Back

The ball's gravitational potential energy is converted into kinetic energy.

Front

At which points does a weight on a spring have the most kinetic energy?

Back

B and D.

Front

What happens to the cars' kinetic energy as they move away from each other?

Back

The cars' kinetic energy is converted into thermal energy.

Front

What is the effect of friction on the energy of a roller coaster moving up and down a hill?

Back

If there is no friction, the total mechanical energy is conserved.

Front

Define kinetic energy.

Back

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

Front

Define gravitational potential energy.

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field.

Front

What is electric potential energy?

Back

Electric potential energy is the energy a charged object has due to its position in an electric field.

Front

Explain the concept of energy conversion in the context of a bouncing ball.

Back

As the ball bounces, its gravitational potential energy converts to kinetic energy and vice versa.

Front

What is the principle of conservation of energy?

Back

Energy cannot be created or destroyed, only transformed from one form to another.
