Newton's Laws

Front

What is Newton's 1st Law?

Back

An object at rest or moving at a constant speed in a straight path will continue to do so until a net force acts upon it.

Front

What do the letters F, m, and a represent in physics?

Back

F = Force, m = Mass, a = Acceleration.

Front

What is Newton's 2nd Law?

Back

Acceleration is caused by a force acting on a mass, and it can be expressed as F = ma.

Front

What is Newton's 3rd Law?

Back

Forces always act in equal and opposite pairs.

Front

What is the difference between speed and velocity?

Back

Velocity has direction, while speed does not.

Front

What does 'force' mean in physics?

Back

A push or pull on an object.

Front

What is 'mass'?

Back

The amount of matter in an object.

Front

What is 'acceleration'?

Back

The rate at which an object changes its velocity.

Front

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

Back

It continues to move at a constant speed in a straight line.

Front

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

Back

A soccer ball will not move until someone kicks it.
