Conservation of Energy. Energy is conserved in nature.  Energy can not be created or destroyed.
we can convert the energy from one form to other.
In the case of ball thrown vertically, potential energy(PE) keep on increasing and kinetic energy(KE)
keep on decreasing and the total of PE and KE remains same.

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
