... Suppose a 300 lb crate of silly string has to be loaded onto a 1.3 m high silly string delivery truck. Too heavy to lift, a silly string truck loader uses a handy-dandy, frictionless, ramp, which is at a 30º incline. With the ramp the worker only needs to apply a 150 lb force (since sin 30º = ½).

Kinetic Energy and Work
... Work done by a force Power In addition, we will develop the work-kinetic energy theorem and apply it to solve a variety of problems. This approach is an alternative approach to mechanics. It uses scalars such as work and kinetic energy rather than vectors such as velocity and acceleration. Therefore ...
