Work Energy Theorem Worksheet. Be careful, direction of applied net force and direction of motion must be same. Intro to springs and Hooke's law.
After the net force is removed (no more work is being done) the object's total energy is altered as a result of the work that was done.
You should understand the work-energy theorem so you can: Calculate the change in kinetic energy or speed that results from performing a specified amount of work on a body.
It is important to know whether a force is an conservative force or an non-conservative force in the system, because this is related to whether the force can change an object's total mechanical energy when it does. Potential energy stored in a spring. The work-energy theorem can be derived from Newton's second law.
