Correct Answer - Option 4 : p2/2m

Momentum

  • Momentum is defined as the product of the mass and velocity of the body. 
  • It is a vector quantity directed toward velocity. 
  • It is given as 

p = mv      ----(1)

m is mass, v is the velocity, p is momentum

Kinetic Energy

  • The energy of a body in motion due to its state of motion is called kinetic energy. 
  • It is given as 


\(K = \frac{1}{2}mv^2\)        ----(2)

K is kinetic energy, m is mass, v is speed.

Relationship between Momentum and Kinetic Energy

If we combine equation (1) and (2) we will get the relationship between momentum and kinetic energy as

\(K = \frac{p^2}{2m}\)
