Question

If the momentum of an object changes and its mass remains constant,

A. It is accelerating (or decelerating)
B. There is a force acting on it.
C. Its velocity is changing
D. All of the above

Answer 1

I think it's D, but I'm not sure

Answer 2

its a because when you change the mass of an object its "volume" changes as well so basically what im trying to say here since im in a physics class rn, it dont matter if the mass stays or changes, but you gotta look at the other factors in play of the equation if you catch my drift

Answer 4

but yes, the answer is definitely a

Answer 5

@cathrinerose23 thanks

Answer 6

@Hallsville yw

Answer 7

It is not A. The question can be easily answered by analyzing the formula for momentum.

\(\text{p=mv}\)
Where p=momentum in kg m/s
m=mass in kg
v=velocity in m/s

The problem suggests that mass is constant, yet momentum is changing. This means that only velocity can change. A change in velocity is equivalent to acceleration, because a change in velocity over time is acceleration. An object has an acceleration when an unbalanced force acts upon the object. Hence, the answer would be D, you were originally correct @hallsville
