Work and Energy

Work and Energy. Work. Work is said to be done when an applied force, f moves an object thru a distance, d. W = f x d In the metric system, the unit of force is in Newton (N), unit of distance is in meters (m), and the unit of work is in Joules (J). Work. When force is applied

Law of the Conservation of Mechanical Energy

Law of the Conservation of Mechanical Energy. When gravity is the only external influence on an object, its mechanical energy remains constant. FORMULA: (PE + KE) = C where C is some constant value. Law of the Conservation of Mechanical Energy.

Conversion of potential energy to kinetic energy

Runout of a large landslide. Consider a landslide mass that fails from an elevation of 2500 m. The valley floor onto which the rockmass tumbles lies at 1700 m. The mass comes to a screeching halt on the opposite valley wall at an elevation of 1950 m.

Aim: Applications of Conservation of Energy

Aim: Applications of Conservation of Energy. Do Now: A bullet fired from a rifle emerges with a kinetic energy of 2,400 J. If the barrel of the rifle is 0.5 m long, what is the average force on the bullet while in the barrel?. ? KE = W ? KE = Fd 2,400 J = F(0.5 m) F = 4,800 N.
