Newtons Laws Vocab.
Term | Definition |
---|---|
Newton's First Law of Motion | An object at rest stays at rest or an object in motion stays in motion until unbalanced forces act upon it. This us often referred to as Newton's law of inertia. |
Inertia | The tendency of a physical object to remain still or continue moving unless force is applied. |
At Rest | The state of an object when it is not in motion. |
Unbalanced Forces | Forces on an object that cause change in the motion of the object. |
Newton's Second Law of Motion | Acceleration of an object depends on the object's mass and the magnitude of the force acting upon it (F + ma). This is often referred to as Newton's law of force and acceleration. |
Force | A push or a pull that can change the motion of an object. |
Magnitude | The size or quantity of something. |
Acceleration | The rate of change in an object's speed. |
Newton's Third Law of Motion | For every action there is an equal and opposite reaction. This is often referred to as Newton's law of action-reaction. |
Action | The way that something causes a change. |
Reaction | Resistance or force of equal magnitude acting in the opposite direction of an action force. |
