Open in App

Solution

Given equation is $v = u + a t$ .
Simply it is first newton's equation of motion. in the equation:
$u$ = Initial velocity
$v$ = Final velocity
$a$ = Acceleration
$t$ = Time of motion
Equations of motion define the behavior of a physical scheme in order of its movement as a function of the time in Newtonian mechanics.
Mathematical formulas that explain the position, velocity, or acceleration of a body in relation to a specific frame of reference are known as equations of motion.

Q. v^2=u^+2as when u=0 , v^2=2as but when we consider v=u+at , v=at since u=0 . wkt t=s/v which implies v=a(s/v) we get v^2=as how is this possible ?

At constant pressure (∆P=0)

Than, Enthalpy

∆H=∆U+∆(PV)

∆H=∆U+P∆V+V∆P; But as (∆P=0)

∆H=∆U+P∆V

But if the Volume is constant (∆V=0)

Than the equation becomes

∆H=∆U+V∆P
