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 |
