When a workman rotates the sharpening wheel with his leg and places the edge of a knife or scissor on the wheel to sharpen.

Kinetic energy is the energy of a moving object. This is the idea behind a spring used in a wind-up clock or a rubber band used in a wind-up airplane. Although the kinetic and potential energy of an object can change, its mechanical energy remains constant.

This energy sources can be replenished with a short period of time. In the case of electrical energy, the object is the charged particle, and the. Work from such forces must be calculated explicitly.

You store the energy by bending (deforming) the material in a spring, and the material releases the energy as it returns to its original shape. Since mechanical energy is the sum of kinetic and potential energy, mechanical energy is also not conserved. Mechanical energy is the sum of kinetic energyand potential energy.

A satellite orbiting the earth has a speed of 5.5 km/s when its distance from the center of the earth is 11,000 km. Here PE is the electric potential energy. Cause of change of Mechanicl Energy Forces that change the mechanical energy of the system.

Well, that seems simple enough, but what is energy?. Energy can be transferred mechanically through the movement of the parts in machines, and when the motion or position of an object changes. Non-conservative Forces change the mechanical energy of a system, and can arise from internal forces that add or subtract mechanical energy (e.g.
