Newton's Laws of Motion/ Forces Review

Front

What is Newton's 1st 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 2nd 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 3rd Law of Motion?

Back

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

Front

Define 'Force'.

Back

A push or pull exerted on an object.

Front

What is 'Motion'?

Back

A change in position of an object over time.

Front

What is an 'Unbalanced Force'?

Back

Forces that cause a change in the motion of an object; they are not equal and opposite.

Front

What is a 'Balanced Force'?

Back

Forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

How do you calculate force?

Back

Force (F) is calculated using the formula F = ma, where m is mass and a is acceleration.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What is inertia?

Back

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