A uniformly accelerated body has ____(a) Constant speed(b) Constant velocity(c) Constant force(d) Constant momentumThe question was posed to me by my school teacher while I was bunking the class.Origin of the question is Motion in a Straight Line topic in portion Motion in a Straight Line of Physics – Class 11

Answer»

Right choice is (c) CONSTANT force

Explanation: SINCE the body is ACCELERATED, the speed and velocity will vary. Momentum DEPENDS on velocity; hence the momentum will also vary. The force remains constant as F = ma.
