Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is the formula for calculating frictional force?

Back

Frictional force = coefficient of friction × normal force.

Front

What does the term 'normal force' refer to?

Back

The force exerted by a surface perpendicular to the object resting on it.

How does mass affect acceleration when a constant force is applied?

Back

Acceleration is inversely proportional to mass; as mass increases, acceleration decreases.
