Relative Velocity. Example 1 A man is trying to cross a river that flows due W with a strong current. If the man starts on the N bank, how should he head.
Rotation On a coordinate grid. For a Rotation, you need An angle or fraction of a turn –Eg 90° or a Quarter Turn –Eg 180° or a Half Turn A direction –Clockwise.
