Newton's Laws Review

Front

What is Newton's 1st 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 2nd Law of Motion?

Back

Force = Mass × Acceleration.

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

Define 'net force'.

Back

The sum of all forces acting on an object, capable of causing acceleration.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What happens when an unbalanced force acts on an object?

Back

It changes the motion of the object.

Front

What is the formula for calculating force?

Back

Force = Mass × Acceleration.

Front

What is the relationship between mass and acceleration in Newton's 2nd Law?

Back

Acceleration is directly proportional to the net force and inversely proportional to the mass.

Front

What is an action force?

Back

The initial force applied to an object, such as pulling a bowstring.

Front

What is a reaction force?

Back

The force that occurs in response to an action force, equal in magnitude and opposite in direction.
