Newton's Laws

Front

What is Newton's 1st Law?

Back

An object at rest stays at rest, and an object in motion continues in motion with the same speed and in the same direction 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 happens to an object at rest if no outside forces are applied?

Back

It will stay at rest.

Front

What is static friction?

Back

The force that keeps an object at rest and prevents it from moving.

Front

What is sliding friction?

Back

The force that opposes the motion of an object that is sliding over a surface.

Front

If a net force of 8 N is applied to a 2-kg object, what is its acceleration?

Back

4 m/s².

Front

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

Back

The 0.52 kg ball will have the greatest acceleration.

Front

What is the formula for calculating force?

Back

Force = mass × acceleration (F = ma).

Front

What is acceleration?

Back

The rate of change of velocity of an object.
