What is Newton's 1st Law of Motion?

Back

An object at rest remains at rest and an object in motion remains in motion at constant velocity unless acted upon by a net force.

Front

What is Newton's 2nd Law of Motion?

Back

Net force equals mass times acceleration (F = ma).

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What is the unit of force?

Back

Newton (N).

Front

What does inertia refer to in physics?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

How does mass affect acceleration according to Newton's 2nd Law?

Back

As mass increases, acceleration decreases for a given net force.

Front

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

Back

Force is directly proportional to the product of mass and acceleration.

Front

What is an example of Newton's 1st Law in everyday life?

Back

A passenger lurches forward in a car when it suddenly stops.

Front

How does a rocket launch demonstrate Newton's 3rd Law?

Back

The rocket pushes exhaust gases downward, and in response, the rocket is propelled upward.

Front

What is the significance of the net force in motion?

Back

Net force determines the acceleration of an object according to Newton's 2nd Law.
