Work energy theorem physics.

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. If there is no displacement there is no work done. In other words w is telling you the amount of energy that the force f is giving to the object. Thus the work energy theorem describes the reasons behind this physics of no work.

You might get tired if you keep standing for a long time but according to physics you have done zero work. The theorem implies that the net work on a system equals the change in the quantity 1 2mv2 1 2 m v 2. W refers to the work done by the force f. If no displacement of the object occurs work is not done.

The net work done by the forces acting on a particle is equal to 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. The formula to find the work done by a particular force on an object is w equals f d cosine theta. Work is said to be done when an acting force displaces a particle.

The work energy theorem implies that a smaller change in kinetic energy results in a smaller penetration. 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. The work energy theorem explains the reasons behind this physics of no work. Equation 4 is the mathematical representation of an important result called the work energy theorem which in words can be stated as follows.

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 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.
