Question

Under the action of a constant force, a particle is experiencing a constant acceleration. The power is (A) Positive constant (B) Negative constant (C) Increasing uniformly with time (D) Decreasing uniformly with time

Tardigrade Admin · Accepted Answer

Instantaneous power is P=F.v=F at As force and acceleration are constant. So, velocity of the particle must be keep on increasing Hence, power is increasing uniformly with time. i.e. P propto t .

Q. Under the action of a constant force, a particle is experiencing a constant acceleration. The power is

Positive constant

Negative constant

Increasing uniformly with time

Decreasing uniformly with time

Instantaneous power is $P = F . v = F$ at
As force and acceleration are constant.
So, velocity of the particle must be keep on increasing
Hence, power is increasing uniformly with time.
i.e. $P \propto t$ .
