Newton's 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

Force = Mass × Acceleration (F = ma). This law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is Newton's Third Law of Motion?

Back

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

Front

What is net force?

Back

The overall force acting on an object when all the individual forces are combined.

Front

If the mass of an object is doubled, what happens to its acceleration if the same force is applied?

Back

The acceleration is cut in half.

Front

What is the unit of force in the International System of Units (SI)?

Back

Newton (N).

Front

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

Back

Greater mass results in less acceleration.

Front

What is the relationship between force, mass, and acceleration?

Back

Force is the product of mass and acceleration (F = ma).

Front

If a book weighs 4 N and is held at rest, what is the net force acting on it?

Back

0 N.

Front

What happens to the motion of an object if the net force acting on it is zero?

Back

The object will remain at rest or continue to move at a constant velocity.
