Potential & Kinetic Energy Practice

Front

What is potential energy?

Back

The energy an object has due to its position or condition.

Front

What is kinetic energy?

Back

The energy an object has due to its motion.

Front

Which is the best synonym for potential energy?

Back

Stored energy.

Front

How is kinetic energy calculated?

Back

Kinetic energy (KE) = 1/2 * mass (m) * velocity (v)^2.

Front

If a car has a mass of 1000 kg and is traveling at 20 m/s, what is its kinetic energy?

Back

200,000 J.

Front

What happens to kinetic energy if the velocity of an object doubles?

Back

The kinetic energy increases by a factor of four.

Front

What do potential and kinetic energy have in common?

Back

They're both related to motion.

Front

What is gravitational potential energy?

Back

Potential energy related to an object's height and the gravitational force acting on it.

Front

What is the formula for gravitational potential energy?

Back

Potential energy (PE) = mass (m) * gravity (g) * height (h).

Front

What is the relationship between mass and kinetic energy?

Back

Kinetic energy increases with an increase in mass.
