Newtons Laws of Motion

Front

What is Newton's 1st Law of Motion?

Back

Newton's 1st Law, also known as the Law of Inertia, states that an object at rest will stay at rest, and an object in motion will stay in motion at a constant velocity unless acted upon by an outside force.

Front

What is Newton's 2nd Law of Motion?

Back

Newton's 2nd Law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This is often expressed with the formula F = ma (Force = mass x acceleration).

Front

What is Newton's 3rd Law of Motion?

Back

Newton's 3rd Law states that for every action, there is an equal and opposite reaction. This means that forces always occur in pairs.

Front

What does inertia mean?

Back

Inertia is the tendency of an object to resist changes in its state of motion. The more mass an object has, the greater its inertia.

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.

Front

Give an example of Newton's 2nd Law in everyday life.

Back

If you push a shopping cart, it accelerates faster if it is empty than if it is full because the empty cart has less mass.

Give an example of Newton's 3rd Law in everyday life.

Back

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

Front

What is the relationship between mass and acceleration according to Newton's 2nd Law?

Back

According to Newton's 2nd Law, as mass increases, acceleration decreases if the same force is applied.

Front

What happens to an object in motion if no external force acts on it?

Back

An object in motion will continue to move at a constant velocity in a straight line.

Front

What is the formula for calculating force?

Back

The formula for calculating force is F = ma, where F is force, m is mass, and a is acceleration.
