Work+and+Power

= = =Work and Power= Work is the force that must be applied in the same direction as the movement.

Power is the rate at which work is done.

Power = Work/time Work = Force x Distance
 * Watt is the unit of power
 * Power is measured at joules per seconds
 * Work is force times Distance
 * When force is applied to machines you are using work
 * The unit for mearsurement is joules

How many joules of work are done on a golfball by a golfer who sings with a force of 10N and sends the ball 80M? A: w=fxd 10x80= 800J

How much work is done using a 60-Watt light bulb for 120 seconds? A: P=w/t pxt=w 60x120= 7200J
