Newton's Laws of Motion

Front

What is Newton's 1st Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced 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. This is often expressed as the formula F = ma.

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What is the Law of Inertia?

Back

It is another name for Newton's 1st Law, emphasizing that objects resist changes to their state of motion.

Front

What does the term 'net force' mean?

Back

The overall force acting on an object when all the individual forces are combined.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can be caused by a change in speed or direction.

Front

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

Back

As mass increases, acceleration decreases for a given force; heavier objects require more force to accelerate.

Front

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

Back

A book resting on a table will remain at rest until someone picks it up.

Front

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

Back

A soccer ball will accelerate more when kicked harder (greater force) and less when kicked gently.

Front

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

Back

When you jump off a small boat, you push down on the boat, and the boat pushes you up into the air.
