Newton's Laws

Front

What is Newton's 1st Law?

Back

An object at rest will stay at rest, and an object in motion will stay in motion at a constant speed in a straight line unless acted upon by a net external force.

Front

What is Newton's 2nd Law?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. (F = ma)

Front

What is Newton's 3rd Law?

Back

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

Front

What does 'F' stand for in the equation F = ma?

Back

Force.

Front

What does 'm' stand for in the equation F = ma?

Back

Mass.

Front

What does 'a' stand for in the equation F = ma?

Back

Acceleration.

Front

If a 2 kg object has a net force of 8 N acting on it, what is its acceleration?

Back

4 m/s².

Front

Which ball will have greater acceleration if a force of 26 N is applied: a 0.52 kg ball or a 0.78 kg ball?

Back

The 0.52 kg ball will have the greatest acceleration.

Front

What happens to an object at rest if no outside forces are applied?

Back

It will stay at rest.

Front

What is the relationship between mass and acceleration when a constant force is applied?

Back

As mass increases, acceleration decreases.
