Newton's Laws Raines
vocab for physics
| Question | Answer |
|---|---|
| Newtons first law | Objects would stay still until you apply force . Objects would stop moving until you stop applying force |
| Newtons second law | Force = Mass x Acceleration |
| Newtons third law | For every action there is an equal and opposite reaction |
| What is the unit for acceleration | M/s2 |
| What is the unit for mass | kg (kilograms ) |
| What is the unit for force | N (Newtons) |
| Speed | distance over time |
| mass | the amount of matter in an object |
| inertia | an object's tendency to move in a direction |
| Force | a push or a pull |
| acceleration | a change in speed over time |
| velocity | speed and direction |
| Vector | a direction |
| momentum | inertia in motion |
| impulse | units of forts multiplied by units of time. |
| SI | International Standard |
| centi | 100 |
| milli | 1,000 |
| deci | 10 |
| Kilo | 1,000 |
| Gravitational Constant (G) | 6.67408 × 10^-11 |
| Approximate gravitational force formula | F~ m1 x m2/d^2 |
| Exact gravitational force formula | F= G m1 x m2/d^2 |
| Newton's synthesis | Newton found that the laws of gravity works the same in space as well as earth. |
| What kind of things determine gravitational force? | Mass and distance |
| Electrical Energy | When electrons move through a wire. |
| Radiant (Light) Energy | Different types of light (Colors, microwaves, radio waves) |
| Nuclear Energy | Energy from the splitting and bonding of atoms. Fission and Fusion |
| Thermal Energy | Heat caused by moving atoms |
| Chemical | Energy stored in matter. (Ex. Fuel, food, explosives) |
| Elastic Energy | Energy from compressing or stretching (crushing or pulling) |
| Sound Energy | Vibrations of Matter |
| Gravitational Energy | Energy that comes from falling from high places |
| Mechanical Energy | When something moves. |
| Kinetic Energy | Energy in motion |
| Potential Energy | stored energy |
