Forces

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What happens when two forces act in the same direction?

Back

You add the forces together to find the net force.

Front

What is force measured in?

Back

Newtons (N) is the unit of force.

Front

What does it mean when we say forces act in pairs?

Back

For every force, there is a force that is equal in size but opposite in direction.

Front

If a 10 kg object accelerates at 15 m/s², what is the force applied?

Back

150 Newtons.

Front

What is the net force when two equal forces of 5 N act in the same direction?

Back

10 Newtons.

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.

Front

What is the formula to calculate force?

Back

Force = mass × acceleration (F = m × a).

Front

What happens to an object at rest according to Newton's 1st Law?

Back

It stays at rest unless acted upon by a force.

Front

What is an example of a balanced force?

Back

A book resting on a table, where gravity pulls it down and the table pushes it up.
