Hi, my name is Aprameya i had a doubt we know K.E.(Kinetic Energy) = (1/2)mv^2 the v over here is velocity but at what time. Velocity will be different at differnt points of time i mean at 1second it might be something and and at another second it might be something else. so while calculating which velocity do we use
