The mathematical expression for work depends upon the particular circumstances. Workdonein compressing a gas at constanttemperaturemay be expressed as the product of pressurePtimes the change in volumedV; that is,W=PdV. Work done by atorqueTin rotating a shaft through an angle φ may be express...
If an elastic spring (obeying Hooke's Law) is acting on the particle, the work done by the spring is Where: k is the spring constant s1 is the amount the spring is stretched or compressed from its equilibrium (unstretched) length, at position A ...
The survey found that members of the inpidualist group reached the best solution more often than the constant collaborators, but had a poorer average result. The intermittent collaborators found the right result as often as the inpidualists, and got a better average solution.When it comes to ...

Example question:What is the amount of work done on a spring when it is compressed from its natural length of 1 m to a length of 0.75 m if the spring constant (stiffness of the spring) is k = 16 N/m? This is a good example since a spring requires increasing levels of work as it...
Here, $k$ = spring constant and $x$ = stretch or compression in the string 7. Mechanical energy and its conservation The total mechanical energy of the system is conserved if the forces doing work on the system are conservative i.e, when net work done by external non-conservative force ...
-kx where, k is the spring constant x is the displacement of the object attached we can see that this force is proportional to the displacement of the object from the equilibrium position, hence the force acting at each instant during the compression and extension of the spring will be ...
The spring constant was determined with an accuracy of approximately ±2.5 N/m. The spring constant of the beam with the attached sphere of R = 1 mm was k = 147 N/m, and the spring constant of the beam with the attached sphere of R = 3 mm was k = 109 N/m. Since the sphere ...
WORK AND CONSTANT FORCE 1. How much work is done by the gravitational force when a Hint: The force and the displacement are both 265-kg object falls 2.80 m? downwards, so the angle between them is 0o .2. A 65.0-kg physics student climbs a flight of stairs 20.0 m ...
The previous step was just to explain how this formula is obtained. To solve for the work done, we will need to evaluate this equation at 0.6m and 0.3m and find the difference between those two points. Because the force that is stretching the spring must be acting i...
