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 |
Declaration | 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 |
Newton's 1st Law of Motion | an object that is at rest will stay at rest less an outside an outside force acts upon it. An object in motion will stay in motion unless an outside force acts upon it . |
Newton's 2nd Law of Motion | the net force on an object is equal to the rate of change. (force= mass x acceleration) |
Newton's 3rd 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 Net Force | when the force cancel out and are balanced |
