Work & Kinetic Energy

Work & Kinetic Energy. When work is done on an object, it may give it kinetic energy. In general,. work done = Fd = energy transferred = E k gained by object = ? E k Or ? KE. A formula for E k. Since W = Fd and F = ma then W=mad Recall V f 2 =V i 2 +2ad If object is at rest then.
