Power =
work done
Time interval
Mechanical energy
the energy due to the position of something or the movement of something
potential energy
the energy that is stored and held in reading it
gravitational potential energy =
weight X height ( PE = mgh)
kinetic energy =
1/2 mass X speed squared
kinetic energy
depends on the mass of the object as well as its speed
Net force X distance =
kinetic energy
Work =
Change (KE)
work-energy theorem
work equip change in kinetic energy
work
the effort exerted on something that will change its energy
work =
force X distance
conservation of energy
energy cannot be created or destroyed it may be transformed from 1 form into another but the total amount of energy never changes
Efficiency =
useful energy
output
Total energy input
