Question

what is work- energy theoru
m ? prove it for constant force.​

Answer 1

Answer:-

work energy theorem for a constant force.:-

Consider a force F acting on a body of mass m. The body moves with an acceleration a work done in moving the body to distance,

x = F.x = max---------⟶ (1)

change in K.E of body = 1 /2 mav^2

V^2 = μ^2 + 2as ⇒V ^2 = 2ax

⇒ΔK.E = 1/2 m.2ax = max....... same as (1)

Thus Work done = Change in Kinetic energy

(Work energy theorem).
