How is kinetic energy related to work

Search for:. Work-Energy Theorem. Learning Objectives Outline the derivation of the work-energy theorem. Work transfers energy from one place to another or one form to another. In more general systems than the particle system mentioned here, work can change the potential energy of a mechanical device, the heat energy in a thermal system, or the electrical energy in an electrical device. Key Terms torque : A rotational or twisting effect of a force; SI unit newton-meter or Nm; imperial unit foot-pound or ft-lb.

This article is necessary to state the relationship between work and energy. Work is done when force is applied for moving an object. Work can also be described as the activity that involves a movement and force in the force's direction. For example, when you kick a ball, you exert an external force called F, causing it to move at a certain distance. This change in the ball's position from A to B is called the displacement d.

Work is calculated by multiplying the force applied to the object by the movement of the object. Energy is the capacity to do work. The formula for Potential Energy is mgh, where m is the object's mass, g is the gravitational force, and h is the height that the object covered. Energy cannot be created or destroyed. Energy can only be transferred from one form to another.

There are various types of energy , and all of them are either kinetic or potential. Energy in motion is termed Kinetic Energy, and the one stored in an object is termed Potential Energy. What are some examples of displacement? How are force, energy, and work are related?

How can I calculate the displacement of an object? How do you calculate the displacement of water? How do you calculate the force of gravity between two objects? Why is work negative? How much force was applied? How can I calculate the amount of work done when moving a N crate a distance of 20 meters?
