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.

When work is done on an object, it may give it kinetic energy.
In general, work done = Fd = energy transferred = Ek gained by object = Ek Or KE
A formula for Ek Since W = Fd and F = ma then W=mad • Recall Vf2=Vi2+2ad • If object is at rest then
Summary: • If an object starts at rest, the work done is the total Ek of the object.
Summary: • If an object is already moving, the work done is the change in Ek of the object.
