Describe three forms of mechanical energy?

We don't know what they mean by "forms". Sound is a form of mechanical energy, as it represents the transmission of mechanical vibrations through a material substance. Water waves carry a form of mechanical energy, and the dissipation of that energy on a beach (for example) can cause erosion. The expansion of a cylinder in an engine represents mechanical energy that was derived from the thermal energy of the fuel's combustion.

I'll give you two - Force times linear displacement - Force times angular displacement Okay three: - KE = (1//2)mv^2 Okay four: - PE = mgh The last two are only mechanical because mass is involved, There's work done by friction, too.

There are only two forms as far as I know, kinetic energy and potential energy. Kinetic energy is had by an object in motion, potential energy is present in an object at rest. Did you mean three examples of mechanical energy? KE = (1/2)mv^2, where m is mass, and v is velocity PE = mgh, where m is mass, g is gravity, and h is height
