Ok, I'm trying to help my son with this test question he got wrong. He is in a basic high school physics class and I have virtually no experience with physics. The book and classroom handouts have nothing that completely explains this question. Any help and explanation would be most wonderful!
An arrow is shot straight up into the air and then falls back down to the ground. On the way up , the arrow could be described as...
A) Positive inertia, positive velocity, positive acceleration and positive momentum. (he marked this and got it wrong)
B)Negative inertia, positive velocity, positive acceleration and negative momentum.
C) positive inertia, negative velocity, negative acceleration and positive momentum
D) Positive inertia, positive velocity, negative acceleration and positive momentum. (we think this might be the correct answer but are not sure why)
