Back

A force that does not change the motion of an object.

Front

What is an unbalanced force?

Back

A force that causes an object to accelerate.

Front

What type of energy is present when a person is climbing a ladder?

Back

Both potential and kinetic energy.

Front

According to Newton's first law of motion, what happens to an object at rest if no external force acts on it?

Back

It will remain at rest.

Front

What does Newton's second law of motion state about the relationship between force, mass, and acceleration?

Back

Force is the product of mass and acceleration.

Front

What is kinetic energy?

Back

The energy an object possesses due to its motion.

Front

What is potential energy?

Back

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

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is the unit of force in the International System of Units (SI)?

Back

Newton (N).
