If a curve is drawn expressing the K.E. of a particle as a function of the distance on x-axis. The slope of this curve represents the instantaneous
velocity
Acceleration
force
power
Conceptual W = F.S
Slope : ⇒Workdisplacement = Force---(1) from work energy theorem , work done =change in KE---(2) substitute eqn (2) in (1) KEdisplacement=Force=slope of the curve k.Es=mv22s=ma=Force ∵acceleration =v22s
