Who discovered the 3 laws of motion? |
Sir Isaac Newton |
|
|
1st Law of Motion |
Inertia; An object at rest will stay at rest unless moved by an unbalanced force |
|
|
Unbalanced Force |
A force able to stop an unmoved object |
|
|
2nd Law of Physics |
Force equals Mass multiplied by the acceleration (F=ma) |
|
|
3rd Law of Physics |
For every action, there is an opposite reaction |
|
|
Net Force |
Sum of all forces on an object |
|
|
Balanced Force |
A net force of 0 |
|
|
Equilibrium |
When all forces cancel each other out |
|
|
Normal Force |
When there is an object or surface canceling forces out |
|
|
Speed |
Distance/Time |
|
|
Distance |
Speed*Time |
|
|
Time |
Distance/Speed |
|
|
Velocity |

|
|
Acceleration |

|
|
