When an object moves under the influence of a force, then work is done according to the equationwhere W is the work done, F is the force (N) and s is the displacement (m) in the direction of the force. The SI unit of work is the joule (J), which is a scalar quantity defined...
To solve for power given work and time:Ensure you have the work done and the time in compatible units, typically joules for work and seconds for time. Apply the values to the equation: P = W / T. Divide the work by the time to find the power....
Work,Energy and Power Work, Energy and Power Work Done by a force is defined as the product of the force and displacement (of its point of application) in the direction of the force W = F s cos θ Negative work is said to be done by F if x or its compo. is anti-parallel to ...

The definition of efficiency of human movement has often been unable to cope with activities such as level gait because the numerator of the efficiency equation includes only external work done by the body on an external load. The major purpose of this paper is to propose a definition that not...
We understand from the work equation that if there is no displacement, there is no work done, irrespective of how large the force is. To summarize, we can say that no work is done if: the displacement is zero the force is zero the force and displacement are mutually perpendicular to each...
For example, if the predicted maximal heart rate is 200 beats per minute (BPM) and the test target heart rate of 90% of 200 BPM is achieved at a work load of 8 METs, then the max functional capacity may be estimated from the equation: 8 METS = 90% of maximal functional capacity; ...
When we first learned about work, we were told that the amount of work done on an object is equal to the force on that object over the distance it is displaced. Simplified, we can write this equation as work = force x distance. This sounds pretty good, right? But there's a ...
The amount of work done upon an object depends upon the amount of force (F) causing the work, the displacement (d) experienced by the object during the work, and the angle (theta) between the force and the displacement vectors. The equation for work is .
