Static torque is basically an applied force, but applied about a centre instead of in a straight line.
Dynamic torque, such as that produced by an engine, is a force translated from a straight line (piston) to a circular path (crank) and since its a force at a velocity, its rated as power.
rotational energy
The way I understand it, torque is unrelated to energy, despite the fact that torque and energy happen to have the same dimensions, namely force x distance (in units: newton x meters). In other words, torque is not an energy; it is a different kind of measurement.
Torque is a form of energy, rotational energy. Rotational energy ultimately turns the wheels on the road. The larger the torque the easier wheels turn against resistance. Rotation is also important in airplanes, windmills and ships. Torque T=FxR where F is the force and R is the radius of the "wheel." In general Energy is E= -FRcos x + FRsin x, Torque is FRsin x, the vector energy and FRcos x is called the "work energy". It would be more reasonable to call them real and vector energy, rather than work and torque and together they make quaternion energy.
it intial power is low and did not produce much energy
Torque is vector energy and moment is the time integral of force.
Torque is vector energy. Physicists have mistakenly defined energy as a scalar. Energy is a quaternion consisting of scalar energy (potential) and vector energy (torque). The units of torque is Joules or Newton meter, the same as work or energy..Here is the correct definition of Energy = FD = -F.D + FxD where F is force vector in Newtons and D is displacement vector in meters.F.D = - FDcos(Angle) is the Work or scalar energy and FxD=FDsin(Angle) is the Torque or vector energy. If the angle between the force and displacement is 90 degrees there is only torque; if the angle is a zero degrees there is only work or scalar energy ; if the angle is not a multiple of these two angles there is both scalar and vector energy; work and torque. E.g FD= -Fdcos(45) + Fd sin(45) gives work and torque.
torque.
Yes, weight is a measurement and torque is power. (just think kinetic energy)
torque
The motor changes electrical energy into mechanical (torque) energy.
Yes, torque can have a negative value in physics. Torque is vector energy. Torque is the vector analogue of Work involving force (F) and displacement (D) vectors and the angle (FD). For example Work W = -F.D= -|FD|cos(FD) and Toque T = FxD =|FD|sin(FD). Torque can be negative dependent on the sine(FD). Work and torque is an example of the quaternion nature of physics; for example Quaternion energy E = FD = -F.D + FxD, the real energy is called work F.D and the vector energy is called torque, FxD.
