Q. A particle is acted upon by a constant power. Then, which of the following physical quantity remains constant ?

WBJEEWBJEE 2013Work, Energy and Power

Solution:

We have
Power $=$ Rate of doing work $=\frac{d W}{d t}$
or, $P=\frac{d W}{d t}=$ rate of change in $KE$
i.e., $P=\frac{d W}{d t}=\frac{d( KE )}{d t}=$ constant
