Question

Which equation shows the correct relationship between mechanical energy, kinetic energy, and potential energy? ME = KE + PE ME + KE = PE ME = KE – PE ME + PE = KE

Answer 1

Answer:

World Civilization book is lifted to the top shelf of a student locker, then the student supplies the force to do the work on the book. If a plow is displaced across a field, then some form of farm equipment (usually a tractor or a horse) supplies the force to do the work on the plow. If a pitcher winds up and accelerates a baseball towards home plate, then the pitcher supplies the force to do the work on the baseball. If a roller coaster car is displaced from ground level to the top of the first drop of a roller coaster ride, then a chain driven by a motor supplies the force to do the work on the car

Answer 2

ME + PE = KE is the correct answer
