Front

What is acceleration?

Back

Acceleration is inversely proportional to mass.

Front

What principle explains the backward motion of a boat when a person steps forward onto the dock?

Back

For every action there is an equal and opposite reaction.

Front

What are the two factors affecting the magnitude of the force of gravity between two objects?

Back

Back

Acceleration is inversely proportional to mass.

Front

At which point does a cart have the most mechanical energy?

Back

They would all be the same.

Front

Define inertia.

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is Newton's First Law of Motion?

Back

An object at rest tends to stay at rest, and an object in motion tends to stay in motion unless acted upon by a net external force.

Front

What is the formula for calculating force?

Back

Force = mass × acceleration (F = ma).

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field, calculated as PE = mgh.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, calculated as KE = 1/2 mv².
