Work is the energy needed to apply a force to move an object a particular distance, where force is parallel to the displacement. Power is the rate at which that work is done.

Distance. It refers to the numerical measurement of how far an object is from a particular place. Also, in physics, it may refer to the physical length or evaluation based on some criteria. Furthermore, a distance from X to Y is exchangeable with distance from Y to X.
Review the units of work, energy, force, and distance. Use the equations for mechanical energy and work to show what is work and what is not. Make it clear why holding something off the ground or carrying something over a level surface is not work in the scientific sense.
Steps to Calculate the Distance Traveled by an Object Using Work-Energy Theorem. Step 1: Identify the initial and final velocity. Step 2: Identify the mass of the object. Step 3: Identify the...
Here we learn what work and energy mean in physics and how they are related.
In equation form, the translational kinetic energy, \[KE = \dfrac{1}{2}mv^2,\] is the energy associated with translational motion. Kinetic energy is a form of energy associated with the motion of a particle, single body, or system of objects moving together.
If you know the potential energies for the forces that enter into the problem, then forces are all conservative, and you can apply conservation of mechanical energy simply in terms of potential and kinetic energy. The equation expressing conservation of energy is: \(\mathrm{KE_i+PE_i=KE_f+PE_f.}\) .
