Answer 2

Answer:

• The work-energy theorem states that the net work done by the forces on an object equals the change in its kinetic energy
• According to the work-energy theorem, the net work on an object causes a change in the kinetic energy of the object. The formula for net work is net work = change in kinetic energy = final kinetic energy - initial kinetic energy.Answer: suppose a constant force F acting on a body of mass m produces accelaration 'a' in it.
• After covering distance 's', suppose the velocity of the body changes from u 2 v. Explanation: The equation v^2-u^2=2as------- 1
• .It is powerfully simple, and gives us a direct relation between net work and kinetic energy. ... Though the full applicability of the Work-Energy theorem cannot be seen until we study the conservation of energy, we can use the theorem now to calculate the velocity of a particle given a known force at any position.
