Parallelogram Diagram
|
If 2 forces acting at a point are represented in size and direction by the sides of a parallelogram drawn from the point, their resultant is represented in size and direction by the diagonal of the parallelogram

How to make a scale diagram?
|
1) make a scale e.g. 1cm= 100N
2) have ruler and pencil ready 3) draw diagram 4) find resultant force (centre line) 5) convert back to N |

Vector
|
Magnitude
Direction e.g. 100N, downwards |
|
|
Scalar
|
Magnitude
e.g. mass, energy |

|
Friction
|
def: force that opposes one surface moving
*if amount of friction equals the amount of force applied, object wont move |
