The work-energy theorem is a fundamental principle in physics that states that the work done on an object by a net force is equal to the change in the object's kinetic energy.
The equation for the work-energy theorem is W = ΔKE, where W represents the work done on the object and ΔKE represents the change in kinetic energy.
The work-energy theorem can be applied in various real-world situations, such as calculating the work done by a force on an object in motion, determining the force needed to accelerate an object to a certain speed, or understanding the energy transfer in simple machines.
While the work-energy theorem focuses on the relationship between work and kinetic energy, the law of conservation of energy states that energy can neither be created nor destroyed, only transferred or converted from one form to another.
If the work done on an object is zero, then according to the work-energy theorem, there will be no change in the object's kinetic energy. This could mean that the object is not moving, or that the net force acting on the object is zero.
