Force & Motion 2
Term | Definition |
---|---|
constant speed | The same amount of distance is covered by the object in the same amount of time at each measurement of that same interval. |
deceleration | Decreases the rate of speed. |
gravitational force | A force of attraction between all masses in the universe. |
inertia | The resistance of any physical object to any change in it`s motion |
Newtons first law of motion | An object that is at rest stays rest,an object in motion stays motion till interuption |
Newtons second law of gravity | The net force on a object is equal to the rate of change.(force=mass x acceleration) |
Newtons third law of motion | For every action there is an equal and opposite reaction. |
relative position | A point defined with reference to another position,either fixed or moving. |
velocity | The speed and direction of an abject. |
zero net force | when the forces cancel out and are balanced. |
