3. THE PRINCIPIA  In 1687 Sir Isaac Newton published his most important work.  This work described the 3 laws of motion as well as universal gravity.

4. LAWS OF MOTION  Isaac Newton developed 3 laws of motion

5. 1 ST LAW

6. 2 ND LAW  The force of an object comes from its mass and its acceleration.

7. 3 RD LAW  For every force acting on an object, there is an equal force acting in the opposite direction.

8. GRAVITY  Legend says that Sir Isaac Newton got his inspiration for Gravity when he saw an apple fall from a tree at home.  Gravity is an important force. It keeps us on the floor, without gravity we would be floating around.  Gravity is like a magnet because it pulls things down.  Gravity is a force of attraction.

9. SUMMARY  Sir Isaac Newton was a famous scientist and mathematician  He was born and lived in England  In 1687 he published “The Principia” containing concepts and theories of motion and gravity.  The theory of gravity was inspired from watching an apple fall from a tree.
