9. The Framing Routine The First Law of Motion is… First Law – Law of Inertia What are some important details about the first law? The laws states: “An object in motion tends to stay in motion and an object at rest tends to stay at rest…unless acted on by an outside force.” Inertia is the property of an object to maintain its current state of motion. Inertia is closely related to mass. Friction is a common force that causes objects to slow down. A force must occur to change an object’s speed and/or direction.

13. The Framing Routine The Second Law of Motion is… Second Law – Law of Acceleration What are some important details about the second law? The law states: “Force equals mass times acceleration.” F = m·a This law is the mathematical relationship between force, mass, and acceleration. If mass is the same, force and acceleration are directly proportional…which means… F stands for the net force. Be sure to calculate the net force first. If force is the same, mass and acceleration are inversely proportional…which means…

16. The Framing Routine The Third Law of Motion is… Third Law – Law of Action/Reaction What are some important details about the third law? The law states: “For every action there is an equal and opposite reaction.” To find action/reaction pairs use the following recipe: Action/reaction pairs are always equal and opposite. Action/reaction pairs act on different objects. A exerts a force on B. B exerts a force on A. Action/reaction pairs do not cancel out.

17. The Framing Routine The Third Law of Motion is… Third Law – Law of Action/Reaction What are some important details about the third law? Although the forces are the same, differences in mass cause differences in accelerations…which is what we perceive when looking at a situation. _______________________________________

22. NEWTON’S LAWS My first law of motion explains all you need to know about inertia: Newton’s First Law of Motion (a.k.a. Law of Inertia) “An object in motion tends to stay in motion, and an object at rest tends to stay at rest…unless acted on by an outside force.”

23. NEWTON’S LAWS My second law of motion explains, mathematically, how forces affect motion: Newton’s Second Law of Motion (a.k.a. Law of Acceleration) “Force equals mass times acceleration.”

24. NEWTON’S LAWS My third law of motion explains the interaction of objects and forces: Newton’s Third Law of Motion (a.k.a. Law of Action/Reaction) “For every action, there is an equal and opposite reaction.”
