Work Energy Theorem In Electrostatics

In this live gr 12 physical sciences show we take a look at the work energy theorem.

Work energy theorem in electrostatics.

Not that place you go to earn money. It states that the work done by all external forces is converted into a change of kinetic energy. Where w g work done by gravity. The formula to find the work done by a particular force on an object is w equals f d cosine theta.

In physics it means something else. W n work done by a normal. Where w is the work done by object measured using joules. The amount of energy transferred by a force is called the work done by that force.

W refers to the work done by the force f. In this lesson we revise different types of energy we define work as well as discuss the relationship between work and energy. Actually energy is on. Also here the work done is the work done by all forces acting on the body like gravity friction external force etc.

Electricity magnetism electromagnetism. The work energy theorem can be derived from newton s second law. It turns out that kinetic energy and the amount of work done in the system are strictly correlated and their relation can be described by the work energy theorem. Thus the work energy theorem states that.

Electricity magnetism electrostatics. Not like in the groovy sense. 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. For example consider the following figure according to work energy theorem work done by all the forces change in kinetic energy.

Physical sciences grade 12. W g w n w f k f k i. V i is the initial velocity of an object measured using m s. Work is the product of force and displacement in physics a force is said to do work if when acting there is a movement of the point of application in the direction of the force.

W δke ke ke. Work transfers energy from one place to another or one form to another. M is the mass of the object measured using kilograms. In order to transfer energy to an object you ve got to exert a force on that object.

V f is the final velocity of an object measured using m s.
