WebWhat is force * velocity? Force-velocity relationship The force that the muscles can produce decreases at a given pre-determined velocity (computer-controlled in vivo isokinetic/isovelocity modalities) as that velocity increases. The F-V relationship assumes that at a given velocity, the muscles are generating the maximum force possible. WebThe inertia of a system is equal to the sum of the individual inertias. So, if all three disks have identical inertias, then the inertia of the system has to be three times the inertia of one disk.

WebThe work-energy theorem relates the rotational work done to the change in rotational kinetic energy: WAB = KB − KA where K = 1 2Iω2. The power delivered to a system that is rotating about a fixed axis is the torque times the angular velocity, P = τω . Key Equations Problems A wind turbine rotates at 20 rev/min. WebHow do you find the velocity? Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) over the change in time (Δt), represented by the equation v = Δs/Δt. Speed (or rate, r) is a scalar quantity that measures the distance traveled (d) over the change in time (Δt), represented by the equation r = d/Δt.
