Work
The product of the net force on an object and the distance through which the object is moved. work = net force x distance, W = Fd
joule
unit of measurement for work, the newton-meter (N×m)
When is work done on an object?
When a force acts on an object and the object moves in the direction of the force.
Power
The rate at which work is done.
How can you calculate power?
Power equals the amount of work done divided by the time interval during which the work is done.
power = work done / time interval, P = W/t
