|
Newton 1st Law of Motion |
An object will remain at rest until acted on by an unbalanced force |
|
|
Newton 2nd Law of Motion |
Acceleration is produced when a force acts on a mass. The greater the mass, the greater force needed |
|
|
Newton 3rd Law of Motion |
For every action there is an equal and opposite reaction |
|
|
Work |
When a force causes an object to move in the direction of the force |
|
|
Work Formula |
Force x Distance = Joules |
|
|
Power |
The rate a which energy is transferred |
|
|
Power Formula |
