Front

What is the force acting on a book sitting on a desk?

Back

Gravity is pulling the book down, while the table is exerting an equal and opposite force on the book.

Front

What is the force exerted by a baseball on a bat when the bat hits the baseball with a force of 365 N?

Back

365 N in the opposite direction.

Front

What is potential energy?

Back

Potential energy is the energy that is stored.

Front

If a rocket pushes exhaust with a force of 10,000 N, how much force does the rocket go forward?

Back

10,000 N.

Front

At which point does a ball have the greatest gravitational potential energy (GPE)?

Back

Point A.

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What is the definition of friction?

Back

Friction is the force that opposes the motion of an object.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion.

Front

What is the formula for calculating gravitational potential energy (GPE)?

Back

GPE = mass × gravity × height.

Front

What happens to the potential energy of an object as it falls?

Back

The potential energy decreases as the object falls.
