Question

Shape of graph between speed and kinetic energy of the body is :

• A. Hyperbola
• B. Straight line
• C. Parabola
• D. Circle

Answer 1

The correct option is C Parabola

Kinetic energy $K=\frac{1}{2}m{v}^2$

$\Rightarrow K\propto v^2$

Comparable to equation of parabola $y^2=4ax$

Hence, graph is parabolic in shape.
