When a body is acted upon by a constant net force, its velocity must be
Open in App
Solution
The correct option is B variable
From Newton’s second law, a constant force (F) implies that the acceleration (a) of the body is also constant. Since acceleration is the rate of change of velocity, the velocity must be changing.
