Webb20 feb. 2024 · 7.3: Kinetic Energy. Kinetic energy related to the forces acting on a body and was referred to as “the energy of motion.”. The kinetic energy of a particle is one-half the product of the particle’s mass m and the square of its speed v. 7.4: Work-Energy Theorem. Work-Energy Theorem argues the net work done on a particle equals the change ... WebbSo, the Work Energy Theorem says that, “If a force is acting on a body, a variable force associated with the force is the function G, a variable function of x, whose derivative is the given force.”. Then, at the beginning, if you take the difference of kinetic energy minus the value of G 2, it’ll be the same.
