Transcript of Newton's Laws

Newton's Laws of Motion By: Kelsey Lovell and Lauryn Nilson Newton's First Law Newton's 3rd Law Newton's Second Law The force of an object is equal to the object's mass times its acceleration; an object will move in the direction of the net force. Period 5 3/ 22/13 * An object that is in motion will stay in motion unless a force acts on it. An object that is not moving remains at rest unless something pushes or pulls it. For every action there is an equal and opposite reaction; forces act in pairs MLA Citations Demonstration #1 Carter was an object at rest but was put into motion by an unbalanced force (unbalanced forces cause a change in position, so Kelsey was an unbalanced force). This motion caused him to fall. Newton said that the object would of stayed at rest if not for the unbalanced force. This was the first of his 3 laws. It is also very similar to the the concept in Galileo's concept of inertia. Today, this law is often called the Law of Inertia. Demonstration #2 Demonstration #1 The whiffle ball was easier to throw because the force needed to throw it was less then amount of force needed to throw the soccer ball. Many people consider this Newton's most powerful law because of his immense calculation of dynamics- how velocity changes when the force changes. The more force that is applied, the higher the velocity will be. Demonstration #2 Newton's 2nd law states that acceleration is produced when mass is acted upon by force; the greater the mass is the greater the force will need to be. Olivia had to push harder to move the soccer goal then she had to move the stool. Demonstration #2 Kelsey bounced the trampoline- the result: the flip flop also was bounced. Newton observed that when something in pushed, it will push back with the same amount of force. Kelsey bounced down with a certain level of force and she bounced herself and the flip flop up with the same amount of force. Additional thanks to.... - Mrs. Moorman

-Mrs. Lovell We hope you
enjoyed watching! Action- Kelsey bounced the trampoline
Reaction- the shoe bounced Demonstration #1 Action- Lauryn pulls the rope
Reaction- Kelsey gets pulled because she is also holding the rope "Newton's Three Laws of Motion." Newton's Three Laws of Motion. Dept. Physics & Astronomy- University of Tennessee, n.d. Web. 17 Mar. 2013. The End Newton first publicly introduced his laws in England in 1686. Lauryn was running in motion, but was stopped by an unbalanced force- the tree. This support's Newton's 1st law because Lauryn was in motion and would of stayed in motion if not for the tree. Benson, Tom. "Newton's First Law of Motion."

There are no isolated forces in the universe. Forces exist in pairs, like this example states. When Lauryn pulled the rope, Kelsey was pulled with it. Lauryn's force caused a equal reaction (Kelsey was pulled too). "Newton's First Law." HyperPhysics. Georgia State University, n.d. Web. 17 Mar. 2013. "Newton's 3 Laws of Motion." Newton's Laws of Motion. N.p., n.d. Web. 17 Mar. 2013. Introduction In our project, we demonstrated Newton’s Three Laws of Motion through videos. Sir Isaac Newton, a 17th century genius scientist created three laws of motion (now called Newton's Laws of Motion). His first law states that things in motion will stay in motion and things at rest will stay at rest unless acted by an unbalanced outside force. The 2nd law shows the force of an object is equal to its mass times its acceleration, and lastly in in every action there is an equal and opposite reaction. These laws are still used today and have the changed the way of science forever.
