Efficiency Formula

Efficiency is a measure of how much work or energy is conserved in a process. In many processes, work or energy is lost, for example as waste heat or vibration. The efficiency is the energy output, divided by the energy input, and expressed as a percentage. A perfect process would have an efficiency of 100%.

η = efficiency (Greek letter "eta")

Wout = the work or energy produced by a process. Units are Joules (J).

Win = the work or energy put in to a process. Units are Joules (J).

If an object is standing still, then itsmomentum is zero. To calculate themomentum of a moving object multiply the mass of the object times its velocity. The symbol for momentum is a small p. So, themomentum of the object is calculated to be 8.0 kg-m/s.
