Forces as Vectors

1. Forces as Vectors • Forces are vectors. This means that they have magnitude (size) and direction. • When drawn, vectors are drawn to scale 5N 10N

4. Resolving Vectors • Any vector can be resolved into a number of component vectors.

5. Resolving Vectors • Any vector can be resolved into a number of component vectors.

6. Resolving Vectors • It doesn’t matter what angles you use when resolving forces. But it’s very often useful to resolve them at right angles (90°) to each other.

7. Resolving Vectors • When forces are resolved at right angles you can treat horizontal and vertical motion independently.
