What is the nature of the graph between momentum of a body and its kinetic energy?

Options

  1. AStraight line
  2. BParabola
  3. CCircle
  4. DEllipse

Correct answer

B. Parabola

Step-by-step solution

Let the mass of the body be m and velocity of the body be v , such that it has momentum p and kinetic energy E . Momentum, p=m v p^2=m^2 v^2 Kinetic energy, E= 1 2 m v^2 E= p^2 2 m Hence, the nature of the graph between momentum of a body and its kinetic energy is parabola. i.e., E p^2
