What are Newton's 3 Laws?

Back

1. Law of Inertia: An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an external force. 2. Law of Force and Acceleration: The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma). 3. Law of Action-Reaction: For every action, there is an equal and opposite reaction.

What does the 1st Law of Motion state?

Back

An object in motion will stay in motion and an object at rest will stay at rest unless acted upon by an outside force.

Front

What is friction?

Back

Friction is the resistance that one surface or object encounters when moving over another.

Front

What factors affect the amount of friction between two surfaces?

Back

The types of surfaces in contact and the force pressing them together.

Front

What effect does friction have on a moving object?

Back

It causes the moving object to slow down and eventually stop.

Front

What is the direction of the friction force?

Back

The friction force acts in the opposite direction to the motion of the 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 Newton's 3rd Law of Motion?

Back

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

Front

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

Back

As mass increases, acceleration decreases if the same force is applied.

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

Back

A soccer ball remains at rest until a player kicks it.
