Work Energy Theorem Physics

You might get tired if you keep standing for a long time but according to physics you have done zero work.

Work energy theorem physics. The amount of energy transferred by a force is called the work done by that force. The work energy theorem states that the net work done by the forces on an object equals the change in its kinetic energy. This definition can be extended to rigid bodies by defining the work of the torque and rotational kinetic energy. Thus the work energy theorem describes the reasons behind this physics of no work.

Image will be uploaded soon work is said to be done when force acting on an object displaces the object. The theorem implies that the net work on a system equals the change in the quantity 1 2mv2 1 2 m v 2. The principle of work and kinetic energy also known as the work energy theorem states that the work done by the sum of all forces acting on a particle equals the change in the kinetic energy of the particle. You will understand more of the physics in this interesting article after you finish reading angular momentum.

If no displacement of the object occurs work is not done. This expression is called the work energy theorem and it actually applies in general even for forces that vary in direction and magnitude although we have derived it for the special case of a constant force parallel to the displacement. The work energy theorem explains the reasons behind this physics of no work. The net work done by the forces acting on a particle is equal to the change in the kinetic energy of the particle.

In physics work is the process of energy transfer to the motion of an object via application of a force often represented as the product of force and displacement. W refers to the work done by the force f. The work energy theorem implies that a smaller change in kinetic energy results in a smaller penetration. The formula to find the work done by a particular force on an object is w equals f d cosine theta.

A force is said to do positive work if when applied the force has a component in the direction of the displacement of the point of application. In other words w is telling you the amount of energy that the force f is giving to the object.
