Newtons law
Lesson 10: Newtons Law Vocabulary and Examples
| Term | Definition |
|---|---|
| Newtons 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 is 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 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 |
| Newtons First Law of Motion | A flag fluttering in the wind. |
| Inertia | A rock rolling down a hill. |
| At Rest | A basketball sitting on the gym floor. |
| Unbalanced Forces | Knocking a book off of a desk |
| Newton’s Second Law of Motion | A roller coaster going up and down. |
| Force | Moving a couch to a different area. |
| Magnitude | An airplane flying |
| Acceleration | A fighter jet lifting off of the ground |
| Newton’s Third Law of Motion | A rocket launching off the ground. |
| Action | throwing a baseball. |
| Reaction | Knocking over dominoes. |
