# Newtons Laws of Motion

### Nicole McAllister Period:5

## Newtons 2nd Law of Motion

In this law the direction of the force vector is the same as the direction of the acceleration vector.

## Newtons 3rd Law of Motion

For every action there is a equal and opposite reaction.

## 1st Law Object in state of rest, airspeed zero. Thrust increases from zero. Weight decreases slightly as fuel burns. Net force (thrust-weight) is positive upward. Rocket accelerates upward and velocity decreases. | ## 2nd Law Force=change of momentum with change of time. Force=in mass X velocity. Force=mass X acceleration.Each has both have magnitude and direction. | ## 3rd Law When the air is let out of the balloon the air will go down and the balloon will go up, so the action (letting air out) will make the reaction (balloon goes up). |

## 1st Law

Object in state of rest, airspeed zero. Thrust increases from zero. Weight decreases slightly as fuel burns. Net force (thrust-weight) is positive upward. Rocket accelerates upward and velocity decreases.

## 2nd Law

Force=change of momentum with change of time.

Force=in

Force=mass X

Each has both have magnitude and direction.

Force=in

__mass X velocity.__Force=mass X

__acceleration.__Each has both have magnitude and direction.
