Newton's Laws of Motion

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

What is a balanced force?

Back

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

Front

What is an unbalanced force?

Back

Forces that are not equal and opposite, resulting in a change in motion.

Front

What unit is used to measure force?

Back

Newtons (N) are used to measure force.

Front

What does the term 'net force' mean?

Back

The overall force acting on an object when all the individual forces are combined.

Front

How does mass affect acceleration according to Newton's 2nd Law?

Back

As mass increases, acceleration decreases for a given force.

Front

What is inertia?

Back

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

Front

Give an example of Newton's 1st Law in everyday life.

Back

A book resting on a table will remain at rest until someone pushes it.
