a constant force acts on a mass "m" at rest .velocity acquired in travelling a fixed distance is directly proportional to ?

Open in App

Solution

force = mass × acceleration'

Constant force means acceleration produced is constant because mass is also constant.

Velocity is given by
v = u+at
As initially object is at rest then u = 0.

v = at
acceleration(a) is constant, Velocity is directly proportional to the time taken in travelling a fixed distance.
