P: power
T: torque
n: RPM
GS: ground speed
TAS: true air speed
Work is the result of a force acting over some distance. Work is quantified in joules (Nm) or foot-pounds.
Torque is a rotating force produced by a motor’s crankshaft. The more torque the motor produces, the greater is its ability to perform work.
Power is the measure of how much Work can be done in a specified time. Power is quantified in watts (J/s) or horse power.
POWER AND TORQUE OF A BODY IN ANGULAR MOTION
The power of a rotating body can be expressed as
P = T x ω
= T x 2 x π x nRPS
= T x π x nRPM / 30
where,
P = power (W)
T = torque or moment (Nm)
ω = angular velocity (rad/s)
π = 3.14...
nRPS = rotations per second (rps, 1/s)
nRPM = rotations per minute (rpm, 1/min)
