Work done on a body is equal to the increase in the energy of the body, for work transfers energy to the body. If, however, the applied force is opposite to themotionof the object, the work is considered to be negative, implying that energy is taken from the object. The units in wh...
Learn the work done formula and understand the application of work integral in the work done formula with examples problems using calculus.
, which is defined as the work done by a force of 1 newton in moving an object through a distance of 1 meter in the direction of the force. a weightlifter lifts a barbell weighing 25 kg and displaces it from the ground by 2 m. here, the work done upon the barbell is against ...
it is very shocking that even though you feel fatigue but work done by you on the wall is zero. the displacement of the wall is zero. so according to the formula, \(\begin{array}{l}w = f.s\end{array} \) \(\begin{array}{l}w = f.0\end{array} \) \(\begin{array}{l}w ...
It is the minimum work needed to separate the phases, and energies needed to break adhesive bonds often exceed this by a significant amount, because of work done in deforming the adhesive layer or the adherends. An example where much work is done on stretching the adhesive is a pressure ...
There is a long-standing need for a direct determination of solid-liquid work of adhesion due to its central role in several scientific and industrial fields. Here, a method is introduced to determine the value of adhesion work on flat surfaces directly,
I have been helping students in Physics, Chemistry, Biology, and Thermodynamics for 5 years. I have completed my all studies in Physics and chemistry at a well-reputed university and am now able to do any task related to Physics and Chemistry.You can surely rely on my w...
Work is a force that is applied over a distance which involves the transfer of energy from one kind to another, whereas power is work done per second. Learn more about the definition of work and power, the rotational equation for work, and the two equations for rotational power. Rotational...
Molecules are essentially charge-aggregators and that creates opportunities for electrostatic attraction and repulsion. The attraction forces have implications on boiling points and other behaviors of molecules and thus are a subject of interest in chemistry....
Work Done = Time Taken × Rate of Work Rate of Work = 1 / Time Taken Time Taken = 1 / Rate of Work If a piece of work is done in x number of days, then the work done in one day = 1/x Total Wok Done = Number of Days × Efficiency ...
