Newton’s Laws of Motion Born: Dec. 25, 1642 Died: March 20, 1726 Location: England Theorized laws of motion Confirmed that the Earth is not the center of the solar system Created formulas to predict planetary motion Father of much of modern mathematics

Newton’s Laws of Motion (1)

First Law An object remains either at rest or in motion unless acted upon by an outside force. Translation If there are no forces acting on an object it will continue doing what its doing.

Newton’s Laws of Motion (1)

Newton’s Laws of Motion (2) Second Law Force (F) = mass (m) X acceleration (a) F = ma Translation The force on an object is equal to its mass times its acceleration.

Newton’s Laws of Motion (3) Third Law For every action, there is an equal and opposite reaction. Translation You push on a wall, it pushes back with the same force.

Gravity Gravity is an acceleration towards the center of the Earth at 9.8 m/s/s

Gravity F = ma Gravity is an acceleration You have a ______ So you experience a ______

Gravity

How do planes fly?

Momentum Momentum = mass X velocity The more mass you have and/or the faster you are going, the more momentum you have.

Egg Drop AKA Project Humpty Dumpty

Egg Drop Goal: Build an apparatus that will protect an egg from a 10 foot drop Materials: You must use ONLY materials on the approved materials list Design: Design you’re apparatus so that it will prevent the egg from cracking when it hits the ground. Time: 2 weeks Rules: Every student will make their own apparatus (help from adults OK, but YOU must build it). NO Parachutes Must fit on a regular sheet of paper ¼ of the egg must be visible the whole time
