force and motion 2
Term | Definition |
---|---|
Constant speed | the same amount of distance is caused by the object in the same amount of time at each measurement of that same interval. |
deceleration | decrease in rate or speed |
gravitational force | the force of attraction between all masses in the universe |
inertia | the resistance of any physical object to any change in its state of motion |
neutrons first law of motion | an object that is at rest will stay at rest unless an outside force acts upon it. an object that is in motion will stay in motion unless an outside force acts upon it |
newtons second law of motion | the net force on an 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 object |
zero not force | when the force cancel out and are balanced |
