1. Sir Isaac Newton & The Three Laws of Motion
5th Grade

2. Sir Isaac Newton He was born in England on December 25, 1643.
He lived for 85 years.
Isaac Newton was raised by his grandmother.

3. Newton’s Education He attended Free Grammar School
Then went on to Trinity College Cambridge
Newton received both a bachelors and masters degree

4. Newton’s Ideas
Newton had new ideas about motion, which he called his three laws of motion.
He also had ideas about gravity, the diffraction of light, and forces.

5. The Three Laws of Motion
Law #1: Law of Inertia
Law #2: F = m x a
Law #3: Action/Reaction

6. Law #1: Law of Inertia
An object at rest will remain at rest unless acted on by an unbalanced force.
An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
This law is often called "the law of inertia".

7. Law #2: F = m x a
Acceleration is produced when a force acts on a mass.
The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object).

8. Law #2: F = m x a
The Second Law gives us an exact relationship between force, mass, and acceleration. It can be expressed as a mathematical equation:
F = m x a
FORCE = MASS x ACCELERATION

9. Law #3: Action/Reaction
For every action there is an equal and opposite re-action.
