| Feb 21, 2019 at 16:06 | comment | added | Andrew Pang | Thanks for all the replies, I think I have a better understanding of it now. Much appreciated. | |
| Feb 21, 2019 at 14:04 | comment | added | BioPhysicist | @AndrewPang I have added more to hopefully convince you to abandon this use of terminology. I would also suggest that instead of trying to change how terminology is typically used just to fit to a poorly worded multiple choice question, you just go ask your teacher about the question and what they really intended. | |

| Feb 21, 2019 at 12:25 | comment | added | JMac | @AndrewPang That question doesn't really make sense as worded. For a), if there were a net force acting on it, that force would cause a change in velocity. The b) one is worded really poorly; because "the forces in all directions are equal" is very unclear. They probably mean opposite directions; but to me, saying "all directions" implies something like a constant pressure acting on all surfaces of the object. The wording on the choices doesn't make much sense as you have it worded there. | |
| Feb 21, 2019 at 11:56 | comment | added | Dale | @Andrew Pang “I am trying to get a better grasp on this concept before i argue” I strongly discourage you from doing that. There is no way you should argue this point. It will only make you seem antagonistic and litigious. | |
| Feb 21, 2019 at 9:24 | comment | added | Jasper | Is it possible that something got lost in translation for b)? I think it could mean "forces in opposite directions are equal". This would be a correct answer, as opposed to a) and current b) | |
| Feb 21, 2019 at 8:12 | comment | added | BowlOfRed | When we say "a force is acting on an object", we almost always mean a non-zero force is acting, even if not stated explictly. Similarly, your a) should probably be read as a non-zero net force. | |
| Feb 21, 2019 at 8:01 | comment | added | Andrew Pang | Thanks for the reply. Yes, I understand what you mean. It is just there was a question on a multiple choice test and it has two choices. The question is: for an object to have a constant velocity; a) there is a net force acting on it. b) the forces in all direction are equal. Technically speaking, i suppose there are real differences based on your explanation. However, I just think there is a net force but it's just zer so the answer would be A. My teacher would probably think the other way, that's why I am trying to get a better grasp on this concept before i argue. | |
