Correct Answer - Option 4 : p
2/2m
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
\(K = \frac{p^2}{2m}\)
