| Inertia | tendancy to resist a change in motion. |
| What is Newton's first Law? | Law of Inertia |
| Formula for Mass? | m = F/a |
| What is the force of gravity on earth? | 9.8 N |
| Newton's second law states that force equals: | mass X acceleration |
| The acceleration of gravity on Earth is equal to: | 9.8 m/s/s |
| How is speed calculated? | Distance/Time |
| Force that always works against the motion that it produces? | Friction |
| A measure of the pulling force of gravity? | Weight |
| A force that pulls every mass toward every other mass? | Gravity |
| The amount of matter in an object; it determines an objects inertia? | Mass |
| Does the mass of an object ever change? | No, mass always stays the same. |
| Does the weight of an object ever change? | Weight changes as gravity changes. |
| Formula for Momentum | P=m*v |
| Formula for Mass (using momentum triangle) | M=P/V |
| Newtons First law. | Object will continue to move in a straight line unless acted upon by an outside force. |
| Newton's Second Law | acceleration is in proportion to force and inversly proportional to mass. |
| Newton's Third Law. | For every action their is an equal and opposite reaction. |
| Example of Newton's First Law. | You are thrown forward when the driver slams on the brakes. |
| Example of Newton's Second Law. | Two objects of different weight dropped at the same time land at the same time. |
| Example of Newton's Third Law. | A rocket uses thrusters to take off from earth. |
