Newton's Three Laws of Motion

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 Newton's Second 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 (F = ma).

Front

What is Newton's Third Law of Motion?

Back

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

Front

What is the formula to calculate force?

Back

F = ma (Force equals mass times acceleration).

Front

What is the unit of force in the SI system?

Back

Newton (N).

Front

What does mass measure?

Back

Mass measures the amount of matter in an object.

Front

What is the symbol for mass?

Back

m.

Front

How do you calculate acceleration?

Back

a = F/m (Acceleration equals force divided by mass).

Front

If a force of 3000 N is applied to an object with a mass of 50 kg, what is the acceleration?

Back

60 m/s².

Front

What is the relationship between mass and acceleration in Newton's Second Law?

Back

As mass increases, acceleration decreases for a given force.
