given
distance d = 30 feet
force F = 5 lbs
Work is done when an object is moved to some distance with appliled force
Energy/work = F * d = 5 lbs 30 ft = 150 ft-lbs

What is the change in potential energy as a result of this move?
An object can possess kinetic energy, the energy of motion, and/or potential energy, the energy of position. Energy can be transferred in many ways, one of which is in the form of work. Work, w, is the energy transferred when an object is caused to move a distance, d, against a force, F. Mathematically, we would write this as w=Fd Force is the product of mass, m, and acceleration, a: F=ma When the acceleration is due to gravity, the symbol...
