Newton's Three Laws

Front

What is Newton's 1st Law of Motion?

Back

An object in motion stays in motion, and an object at rest stays at rest unless acted upon by an external 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.

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

Back

As mass increases, acceleration decreases for a given force.

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = ma).

What happens to an object in motion if no external forces act on it?

Back

It will continue to move at a constant velocity.

Front

What is an example of Newton's 3rd Law in everyday life?

Back

When you jump off a small boat, the boat moves backward as you move forward.

If a 2 kg box and a 4 kg box are pushed with the same force, which will accelerate more?

Back

The 2 kg box will accelerate more because it has less mass.

What is inertia?

Back

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