... A block of mass M = 100 kg slides on a frictional incline plane under gravity. The incline makes an angle θ = 30o with the horizontal. The coefficient of kinetic friction between the mass and the surface of the incline is µk = 0.25. The mass starts from the highest point on the incline plane and rea ...

Electrical Energy And Power, And Emf
... Electricity is generally measured and charged for in terms of electrical energy. The kilowatt-hour (kWh) is defined as the total work done in one hour when the power is 1 kW = 1000 W. 1 kWh = 1000 W × 3600 s = 3.6 × 106 J = 3.6 MJ Note: the kilowatt-hour is a unit of energy (or work) and not power. ...

Energy of a Tossed Ball
... When a juggler tosses a bean ball straight upward, the ball slows down until it reaches the top of its path and then speeds up on its way back down. In terms of energy, when the ball is released it has kinetic energy, KE. As it rises during its free-fall phase it slows down, loses kinetic energy, an ...
