What is the nature of the graph between momentum of a body and its kinetic energy?
- A Straight line
- B Parabola
- C Circle
- D Ellipse
Answer & Solution
Correct Answer
(B) Parabola
Step-by-step Solution
Detailed explanation
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, \(p=m v\) \[ \Rightarrow \quad p^2=m^2 v^2 \] Kinetic energy, \(E=\frac{1}{2} m v^2\) \[ \Rightarrow \quad E=\frac{p^2}{2 m} \] Hence, the…
