Newtons Laws of Motion
Nicole McAllister Period:5
Newtons 1st Law of Motion
Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.
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.
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).
