Newton's Laws of Motion

Front

What is Newton's 1st Law of Motion?

Back

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

Front

What is inertia?

Back

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

Front

What is the net force acting on an object?

Back

The combination of all the forces acting on an object.

Front

What is Newton's 2nd 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 friction?

Back

The force that opposes motion between two surfaces in contact.

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

How do you calculate force?

Back

Force is calculated using the formula F = ma, where F is force, m is mass, and a is acceleration.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity (p = mv).

Front

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

Back

As mass increases, acceleration decreases if the net force remains constant.
