PlanetPhysics/Basic Examples of Calculating Work in Physics

From Wikiversity

Example 1 . Find in the various units (SI, English and CGS) the work done on a mass 112 pounds when lifted through 100 feet.

For this example, the equation for work simplifies to just the force times the distance that the force is acting.

Plugging in the numbers for SI units

Plugging in the numbers for English units

Plugging in the numbers for CGS units

Example 2 . How much mork is done by a force of newtons acting in the x-direction upon a particle while it is displaced from to ?

The force for this example is a function of

integrating from position 1 to 2 yields the work
