10 Circular Motion
... • When an object moves in a circle, even at constant speed, the object still undergoes acceleration because its direction is changing. • This change in direction is due to a net force (otherwise the object would continue to go in a straight line). • Any object moving in a circle undergoes an acceler ...

... Collisions commonly occur in contact sports (such as football) and racket and bat sports (such as baseball, golf, tennis, etc.). Consider a collision in football between a fullback and a linebacker during a goal-line stand. The fullback plunges across the goal line and collides in midair with the li ...

Muscular System notes
... The test for this chapter will not include innervations (i.e. what nerve innervates what muscle). The test will not include questions about arrangement of fascicles. It will not include questions about muscle naming conventions, i.e. no questions about the meaning of word roots such as albus, brevis ...
