Rotational Motion
Rotational motion is everywhere. When you push a door, it rotates. When you pedal a bike, the
wheel rotates. When you start an engine, many parts rotate. Electrons rotate in an atom. H2O

Force and Motion
In previous labs, you used a motion sensor to measure the position, velocity, and acceleration of
moving objects. You were not concerned about the mechanism that caused the object to move,
i.e. the forces that acted on the object.
