Question

If p is the momentum of an object of mass m the expression p^2/ 2m has bade units equal to:
(A) Energy
(B) Power
(C) Force
(D) velocity

Answer 1

We know that ,

p² = m² × v² , Since p = mv

substituting p² value from above equation and dividing by 2 m

$\frac{ {m}^{2} \times v {}^{2} }{2m} \\ \\ = \frac{1}{2} \times mv {}^{2}$
We got the equation of Kinetic Energy!
