Newton's Laws of Motion

Resultant force equals mass times acceleration or F = ma

An object in motion will stay in motion and an object at rest will stay at rest unless acted upon by an external force

To every action there is an equal and opposite reaction

Inertia- the tendency of a body to resist acceleration; the tendency of a body at rest to remain at rest or of a body in straight line

Force- the push or pull on an object

Law #1

Law #2

Law #3

Acceleration- the rate of change of velocity as a function of time.

*Example* If you are holding a glass of water steady the liquid will not move. Once you apply a force and accelerate the glass, the water wants to remain in the same position and can therefore spill out of the glass.

If you are pushing on an object, causing it to accelerate, and then you push, say, three times harder, the acceleration will be three times greater.

When a hammer strikes a nail, the nail exerts and equal and opposite force back on the hammer.
