speed= distance per seconds &
torque= revolution per seconds
Your question is wonderful .... But we are not intelligent enough to answer it ....
Torque is vector energy e.g FxD and momentum is the product of mass and speed p= mv or velocity P=mV. Torque is a vector energy and Momentum is energy per unit speed, a vector or a scalar, W/c = Momentum.
The difference is that constant speed doesn't change but variable speed does. (change)
Velocity is speed with direction
The technical difference is that speed has no direction but velocity has one.

Torque multiplication is proportional to the difference in speed between the impeller and the turbine. for example : At an engine speed of 2100 RPM, and torque at that speed of 100 Newton meters, the torque input to the transmission will be 2.2 times that value - 220 Newton meters with help of torque multiplication.
Torque and speed are inversely proportional
In simple terms, torque gets you moving and power keeps you moving. In other words, your acceleration is dictated by the torque your engine provides and the top speed is limited by the power.
Torque is produced by a phase difference between two windings. The higher the phase difference, the higher the torque.The rotor rotates slightly slower than the magnetic field produced by the stator (the fixed winding). The difference in speed is called the slip and it allows low-frequency currents to be induced in the rotor and torque to be produced. For a motor rotating just below the synchronous speed, the torque is proportional to the slip which is defined by this, where Nis the actual speed and Ns is the synchronous speed:s = 1 - N/Ns
Electromagnetic torque and load torque are different.Electromagnetic torque is the torque that is produced inside the machine which makes the machine rotate,while load torque is the torque that is applied externally with brake drum and and spring balance.Electromagnetic torque can be varied by varying the speed of the machine,but load torque is fixed.
One difference between dynamic torque and static torque is the level of difficulty to measure. Static torque is each to measure, while dynamic torque is not. This is because it requires a transfer of an electric or magnetic effect.
Torque is the measurement of turning force. A wrench applies torque to a bolt. A motor or engine provides torque to do work. Horsepower is the measurement of the work done or ability to do work. This is done by taking the speed the engine is operating at (RPM) and what torque it is producing and applying a formula to give a horsepower rating.
Torque is vector energy e.g FxD and momentum is the product of mass and speed p= mv or velocity P=mV. Torque is a vector energy and Momentum is energy per unit speed, a vector or a scalar, W/c = Momentum.
the ratio of the relative speed of stator magnetic field with the speed of rotor, to the speed of rotor is defined as slip. where as in torque slip characteristic is the graph between the speed of the rotor and the torque experienced on the rotor. in the case of induction motor, the torque decreases with the increase in the rotors speed. while in the case of sychronous motor, its different (you check out, because i just forgot about it!! keep smiling!
The performance curve can be a graph of torque versus speed. The torque is zero at zero speed and also at the synchronous speed. Normally an induction motor operates at 90-97% of the synchronous speed, where the slip is between 10% and 3%. In this region the torque is proportional to the slip. As the torque is increased the speed falls until the motor stalls and the speed drops to zero. Below the stalling speed the torque rises between zero speed and the stalling speed. Because the torque is 0 at 0, a single-phase induction motor needs a separate starting winding fed by a starting capacitor to produce a little positive torque that starts the motor.
power = torque * rpm
