Q. A particle falls from rest under gravity. Its potential energy with respect to ground $(P E)$ and its kinetic energy $(K E)$ are plotted against time $(t)$. Choose the correct graph:

Work, Energy and Power

Solution:

As a particle falls its gravitational potential energy decreases and kinetic energy increases with speed given as $v=g t$ so the possible option is (B).
