Thus the defining equation for work W is given below, where f and s are the magnitudes of the force and displacement, respectively, and &phgr; is the angle between these two vector quantities (see illustration). Because f cos &phgr; · s = f· s cos &phgr; work may be defined ...
whenever work is done, energy is transferred. for a work to be done, in a scientific sense, a force must be exerted, and there must be displacement in the direction of the force. with this said, we can say that work is the product of the component of the force in the direction...
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; ...
Power Formula for Electricity In electricity, power is the rate at which electrical energy is transferred. It is measured in watts (W). The power equation is: P = VI where: P is power in watts (W) V is voltage in volts (V) I is current in amperes (A). This formula tells us tha...
The work done to move a charge in an electric field is equal to the product of the magnitude of the charge and the difference in electric potential between the starting and ending points. This can be represented by the equation W = qΔV, where W is work, q is the charge, and ΔV ...
The work done in rubbing your hands together is equivalent to the amount of heat produced. What principle does this demonstrate? What is a lever? State its principle. What is the principle of electricity generation in windmills? Justify your answer using appropriate Maxwell's equation. What ...
From equation (ii), it is clear that the work done by a force on an object is equal to the change in kinetic energy of the object.FAQs on Derivation of Work Energy Theorem 1. Why is the Work-Energy Theorem important for the students to learn? Work-Energy Theorem is basically a really...

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...
