Derivation of Work-Energy Theorem. Work-Energy Theorem Suppose that an object of mass is moving along a straight line. Last Post; Feb 17, 2013; Replies 2 Views 792. Work-Energy Principle. It states that an object's change in kinetic energy is equal to the work performed on that object. Work transfers energy from one place to another or one form to another. Kinetic energy is a simple concept with a simple equation that is simple to derive. Derivation using algebra alone (and assuming acceleration is constant). First we need to get all of our symbolism out in the open. Deriving x(t) from work-energy theorem. What is the work energy theorem? For a constant torque, the work can be expressed as. The work-energy theorem, also called the work-energy principle, is a foundational idea in physics. Simply it is a relation between work and kinetic energy of a body. The work energy theorem, this is a theorem that states the net work on an object causes a change in the kinetic energy of the object. Last Post; Jun 19, 2005; Replies 2 Views 10K. We call this the Work-Energy Theorem. For pure rotation, the net work is equal to the change in rotational kinetic energy:. Last Post; Oct 20, 2009; Replies 1 Views 3K. So let's review kinetic energy, remember kinetic energy which we'll abbreviate ke is one half the mass times the velocity squared okay.
If and are the the starting and ending positions, and are the the starting and ending velocities, and is the force acting on the object for any given position, then . The work-energy theorem can be derived from Newton’s second law. Work-Energy Theorem: The energy associated with the work done by the net force does not disappear after the net force is removed (or becomes zero), it is transformed into the Kinetic Energy of the body. Hi, Work energy theorem is one of the fundamental theorem in physics.
∆K = W = F∆s = ma∆s. Let's do it twice. Work, which can be negative, is usually expressed in N⋅m, while energy is usually expressed in J. 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.

The work-energy principle is a general principle which can be applied specifically to rotating objects.
Start from the work-energy theorem, then add in Newton's second law of motion.
