Speed =
|
distance divided by velocity
I. Motion |
|
|
Velocity =
|
speed + direction
I. Motion |
|
|
A force
|
is a push or pull
II Forces |
|
|
Magnetism & electricity
|
work with force 9doesn't have to touch)
II Forces |
|
|

|
Force depends on Mass
II Forces |
|
|

|
Slows down moving objects
II Forces |
|
|
Work
|
is done when a force moss an object
II Forces |
|
|

|
|
Newton's 1st Law of Motion
|
An object at rest stays ar rest and an object in motion stays in motion unless a force acts on it.
III Newton's Laws of Motion |
|
|
Newton's 2nd Law of Motion
|
Force = Mass x acceleration (f=ma)
Acceleration = force / mass Mass = Force / acceleration / = divided by III Newton's Laws of Motion |
|
|
Newton's 3rd Law of Motion
|
For every action there is a equal and opposite reaction
