Web15 Sep 2024 · The basic formula for defining power is: [2] Think again about the 100 pound cement block. Moving that block 2 feet in 10 seconds requires twice as much power as moving the same block for the same distance in 20 seconds. Moving the same object faster requires more power. 3 Determine the units you're using for work and power. WebRelation between Torque and Speed. Torque is the rotational equivalence of linear force. Speed measures the distance covered in unit time. The relation between torque and speed is inversely proportional to each other. The torque of a rotating object can be mathematically written as the ratio of power and angular velocity.
