Newton's Laws of Motion

Front

What is Newton's 1st Law of Motion?

Back

An object in motion (or at rest) will stay in motion (or at rest) until an outside force acts upon it.

Front

What is Newton's 2nd Law of Motion?

Back

The acceleration of an object depends on the mass of the object and the amount of force applied. It is expressed as F=ma.

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What does the term 'net force' mean?

Back

The combination of all the forces acting on an object.

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F=ma).

Front

What happens to an object when the net force acting on it is zero?

Back

The object will remain at rest or continue to move at a constant velocity.

Front

What is inertia?

Back

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

Front

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

Back

As mass increases, acceleration decreases if the same force is applied.

Front

What is an example of Newton's 1st Law in everyday life?

Back

A soccer ball will not move until someone kicks it.

Front

What is an example of Newton's 2nd Law in action?

Back

A heavier object requires more force to move it than a lighter object.
