Speed, Torque, and Power

VEX IQ Curriculum - Key Concepts


Speed, Torque, and Power

Speed is a way of measuring how fast an object is moving. Speed measures how far an object will travel over a given period of time. This measure is given in units of distance per time such as Miles per Hour or Feet per Second.


Torque is a force directed in a circle, most often rotating an object. Torque is a spinning force. When torque is spinning an object, the object will create a linear (straight line) force at its edge, such as an axle spinning a tire and causing the tire to move in a straight line along the ground. Torque is measured in units of force × distance, such as Inch-Pounds or Newton-Meters.


Power is the rate at which work is done. With VEX IQ, Smart Motors convert electrical energy into mechanical energy and produce power for a mechanical system. Power is most commonly measured in Watts.


The physical principles of Speed, Torque, and Power all fit together in what engineers call Classical Mechanics. In Classical Mechanics, speed and torque have an inverse (or opposite) relationship – as one increases the other decreases. Higher speed means lower torque, and higher torque means lower speed.


Also, the amount of power supplied has an effect on how much speed and/or torque can be produced in a mechanical system.
