Newton's Laws of Motion

Front

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 is directly proportional to the net force acting on it and inversely proportional to its mass. (F = ma)

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 force?

Back

A push or pull on an object resulting from the object's interaction with another object.

Front

What unit is force measured in?

Back

Newtons (N)

Front

What is friction?

Back

A force that opposes the motion of an object.

Front

How does mass affect acceleration?

Back

If the mass of an object increases while the force remains constant, the acceleration decreases.

Front

What is inertia?

Back

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

Front

What is the relationship between mass and weight?

Back

Weight is the force of gravity acting on an object's mass (Weight = mass × gravity).

Front

What happens to acceleration if the net force is doubled?

Back

The acceleration will also double, assuming mass remains constant.
