Momentum and Energy Practice Flashcard

Front

What is the formula for calculating kinetic energy?

Back

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

Front

What is kinetic energy?

Back

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

Front

Calculate the kinetic energy of a 5 kg object moving at 2 m/s.

Back

10 J

Front

Which of the following is NOT an example of kinetic energy? a book on a shelf, an arrow flying through the air, kicking a soccer ball, chewing gum.

Back

A book on a shelf is NOT an example of kinetic energy.

Front

When is kinetic energy at its maximum for a roller coaster?

Back

At the bottom of a hill.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state.

Front

What happens to kinetic energy when velocity doubles?

Back

Kinetic energy increases by a factor of four (since KE is proportional to the square of velocity).

Front

True or False: A big truck will always have more momentum than a small car.

Back

False.

Front

What factors affect momentum?

Back

Momentum is affected by mass and velocity (Momentum = mass * velocity).

Front

Which has a greater impact on kinetic energy: mass or velocity?

Back

Velocity has a greater impact on kinetic energy.
