Question
What is the form of that graph between
(i) K.E. and velocity for a constant mass?
(ii) K.E. and mass for a constant velocity?
Solution
(i) We have, for a constant mass,
K.E. ∝ v2
Hence, the graph is a parabola.
(ii) We have, for a constant velocity
K.E. ∝ m
Hence, the graph is a straight line.
