Newtons Laws Review
| Question | Answer |
|---|---|
| Newton's First Law of Motion | An object at rest stays at rest; an object in motion stays in motion |
| Newton's Second Law of Motion | An unbalanced force is equal to mass X acceleration (force = mass x acceleration) |
| Newton's Third Law of Motion | For every action force, there is an equal and opposite reaction force |
| Force equals | mass times acceleration |
| Force is measured in units of | Newtons |
| Mass is measured in units of | grams |
| Acceleration is measured in units of | meters per time (seconds or minutes) |
| A ball is thrown at a wall and bounces back is an example of Newtons _____ law | third |
| A ball is thrown further by the stronger person is an exampble of Newtons ________ law | second |
| If you are in a car and it suddenly stops, you will keep moving unless you are wearing a seatbelt, is an example of Newton's _____ law | first |
| For every action there is | an equal ane opposite reaction |
| An object a rest will | stay at rest |
| An object in motion will | stay in motion until a force acts upon it |
| The bigger the mass is of an object | the greater the force will be needed to move it |
| Gravity | the force of attraction between two objects |
| Inertia | objects resistance to change in motion |
| Force | A push or a pull; causes a change in motion |
