Newton Law

Front

What is Newton's First Law of Motion?

Back

A body at rest will remain at rest, and a body in motion will remain in motion unless acted upon by an external force.

Front

What is Newton's Second Law of Motion?

Back

The force acting on an object is equal to the mass of that object times its acceleration (F = ma).

Front

What is Newton's Third Law of Motion?

Back

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

Front

What does it mean when we say 'a body at rest'?

Back

It means that the object is not moving and will not start moving unless a force acts on it.

Front

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

Back

When a car suddenly stops, passengers lurch forward because their bodies want to keep moving.

Front

What is inertia?

Back

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

Front

What is the formula for calculating force?

Back

Force (F) = Mass (m) × Acceleration (a).

Front

What is an example of Newton's Second Law?

Back

If you push a shopping cart, it accelerates faster if it is empty than if it is full.

Front

What does 'action-reaction' mean in Newton's Third Law?

Back

It means that for every force exerted, there is a force of equal size but opposite direction.

Front

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

Back

The greater the mass of an object, the less it will accelerate when a given force is applied.
