Newton's Third Law

The Difference

Scientific Theory - describes how a phenomenon works

​

Scientific Law - ​describes what will happen in a given situation

​

BOTH - provably true​

Science | Newton's Third Law

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

Push or pull on an object.

​

For every action there is an equal and opposite reaction.

Force

For every action there is an equal and opposite reaction.

English scientist; 1643-1727

Isaac Newton

Newton' was one of the first to describe the effects of gravity and the factors that affect gravity (mass and distance between objects)

Gravity

Newton's three laws of motion describe the relationship between forces and motion

Motion

​1 pound is approximately equal to 4.5 Newtons.

​

So if you are 100 pounds, it would take 450 Newtons of force to lift you off of the ground​

​

Pounds to Newtons

The push or pull on an object​

​

The strength of a force is how strong or weak the push or pull is (measured in Newtons - N)​

​Force Definition

For every action there is an equal and opposite reaction.

Question Answers

1. What is a force and what happens when it is exerted on an object?

A force is a push or pull ​on an object; the object accelerates

​

2. When do forces occur?

​When two objects interact

For every action there is an equal and opposite reaction.

Question Answers

3. How are forces described?

​Forces are described using strength and direction.

​

4. How are forces measured and modeled?

​Forces are measured in units called newtons. They are modeled using arrows.
