Physics Work Done and Power

Seite 1

Work done = force x distance --> W is measured in joules, J/ F is measured in newtons, N/ d is measured in metres,m

GPE = MGH --> GPE is the gravitational potential energy in joules, J / m is the mass in kilograms, kg /g is the gravitational field strength in newtons per kilogram, N/kg //h is the change in height in metres, m

KE = ½ × m × v2 --> KE is the kinetic energy in joules, J / m is the mass in kilograms, kg // v is the speed in metres per second, m/s

All moving objects have KE. The KE of an object has depends on its mass – if the mass doubles, the KE doubles, and speed – if the speed doubles, the KE quadruples (increases four times)

P = W/T --> P is power, measured in watts (W) //W is work done, measured in joules (J) // t is time, measured in seconds (s)
