Concept 2.1 Test: Kinetic Energy

Front

What happens to kinetic energy as a ball is thrown up in the air?

Back

The kinetic energy decreases as the potential energy increases.

Front

What two factors are needed to calculate kinetic energy?

Back

Mass and velocity.

Front

What happens to potential energy as a ball falls from a table?

Back

The potential energy decreases as the kinetic energy increases.

Front

At which point on a roller coaster is kinetic energy at its maximum?

Back

Point C.

Front

How do you calculate the kinetic energy of an object?

Back

Kinetic energy = 1/2 * mass * velocity^2.

Front

What is the unit of measurement for kinetic energy?

Back

Joules (J).

Front

What is potential energy?

Back

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

Front

How does height affect potential energy?

Back

Potential energy increases as height increases.

Front

What is the relationship between kinetic energy and speed?

Back

Kinetic energy increases with the square of the speed.

Front

If an object has a mass of 5 kg and is moving at 10 m/s, what is its kinetic energy?

Back

250 J.
