Newton's First Law |
Law of Inertia- An object at rest stays at rest, an object in motion stays in motion.(Unless acted on from an external force) |
|
Newton's Second Law |
Law of Acceleration- Acceleration is directly proportional to the force causing it. Force=Mass x Acceleration. |
|
Newton's Third Law |
Action, Reaction- every action has an equal opposite and concurrent reaction |
|
4 Laws of motion |
No Displacement (stationary)- Center of mass must be over base. Linear Displacement- If forces pass through center of mass, they cause linear motion. Angular motion- if off center they produce rotational(angular) motion. Motion to stationary- Attenuate energy (ex) running into a wall. |
