Biomechanics Section 2 Part 2

Most human movement is _____ a combination of both ___ and ___ motion components.

1. General motion

2. linear

3. angular

What are 3 forms of motion, and describe them?

1. rectilinear: motion along a straight line

2. curvilinear: motion along a curved line

3. angular motion/ rotation: rotation along a imaginary line
