What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

What is Newton's Second Law of Motion?

Back

The acceleration of an object depends on the mass of the object and the amount of force applied. It can be expressed with the formula F = ma (Force = mass x acceleration).

Front

What is Newton's Third Law of Motion?

Back

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

Front

What is inertia?

Back

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

Front

What is friction?

Back

Friction is the resistance that occurs when one surface moves over another.

Front

Who formulated the three laws of motion?

Back

Sir Isaac Newton.

Front

What is a force?

Back

A force is a push or pull acting upon an object.

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes a change in the motion of an object.

Front

What is a balanced force?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).
