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 states that the net work \(W_{net} \) on a system changes its kinetic energy, \(W_{net} = \frac{1}{2}mv^2 - \frac{1}{2}mv_0^2\).
If you transfer a certain amount of energy to an object in motion, what will happen to it? Can you measure the amount of energy in terms of work? How much work does it take to launch a satellite into space? Let us find out the Work-Energy Theorem and answer these questions!
Solve for the angular velocity of a rotating rigid body using the work-energy theorem. Find the power delivered to a rotating rigid body given the applied torque and angular velocity. Summarize the rotational variables and equations and relate them to their translational counterparts.
Use the work-energy theorem to find information about the forces acting on a particle, given information about its motion. We have discussed how to find the work done on a particle by the forces that act on it, but how is that work manifested in the motion of the particle?
Concepts of work, kinetic energy and potential energy are discussed; these concepts are combined with the work-energy theorem to provide a convenient means of analyzing an object or system of objects moving between an initial and final state.
