Question

In which situation would the momentum of a moving object increase?
A: A new force acts on the object, opposing the object’s motion.
B: A force acting in the direction opposite the object’s motion is removed from the object.
C: A force acting in the direction of the object’s motion is removed from the object.
D: Two forces of equal magnitude act on the object in opposite directions.

Answer 1

back in my day these websites had answers-

Answer 2

The correct answer is C: A force acting in the direction of the object’s motion is removed from the object.

Momentum is the product of an object's mass and velocity. According to the law of conservation of momentum, the total momentum of a system remains constant unless acted upon by an external force.

If a force acting in the direction of the object's motion is removed, the object will continue to move with the same velocity but with less resistance, resulting in an increase in momentum.

In contrast, options A and D describe situations where the momentum of the object would decrease, and option B describes a situation where the momentum would remain constant.
