Newton's Laws
8.6A 8.6B 8.6C
Term | Definition |
---|---|
Acceleration | change in speed and / or direction of an object’s motion |
Balanced force | equal and opposite forces on an object that result in no change in position, direction, or motion; net force equals zero |
Friction | the force that one surface exerts on another when the two surfaces rub together |
Inertia | tendency of an object to resist change in motion |
Law of action-reaction | for every action, there is an equal and opposite reaction |
Law of force and acceleration | when an object that has a constant mass is acted upon by a force, the object will accelerate in the same direction as the force applied f=ma |
Law of inertia | the tendency of an object to resist change in motion unless acted upon by a force |
Net force | measurement of the total forces exerted on an object |
Speed | distance traveled by an object in a given amount of time |
Unbalanced force | unequal forces on an object that may result in a change in position, direction or motion; net force does not equal zero |
Velocity | a measurement of an object's speed and direction |
Force | push or pull |
Newton’s First Law of Motion | the tendency of an object to resist change in motion unless acted upon by a force |
Newton’s Second Law of Motion | when an object that has a constant mass is acted upon by a force, the object will accelerate in the same direction as the force applied f-ma |
Newton’s Third Law of Motion | for every action, there is an equal and opposite |
