Question

Data from an experiment shows that kinetic energy is proportional to the square of velocity. Identify the plot of the graph of kinetic energy vs. velocity How it would be :

• A. a straight horizontal line.
• B. a straight diagonal line sloping upward.
• C. a parabola
• D. a hyperbola.
• E. a circle.

Answer 1

The correct option is C a parabola

Let the velocity of the object be $v$.

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

Thus K.E Vs v graph is a parabola symmetric about K.E axis.
