work and energy theorem
Answers
Answer:
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 kinetic energy of the block increases as a result by the amount of work.
Answer:
The Work-Energy Theorem
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. This definition can be extended to rigid bodies by defining the work of the torque and rotational kinetic energy.
(Kinetic Energy: A force does work on the block. The kinetic energy of the block increases as a result by the amount of work. This relationship is generalized in the work-energy theorem.)
The work W done by the net force on a particle equals the change in the particle’s kinetic energy KE:
W=ΔKE
where vi and vf are the speeds of the particle before and after the application of force, and m is the particle’s mass
