I chose not to use the template because this is not a specific homework question. However, it is a problem I face often in my homework problems: How do I determine the direction of velocity? For example, if I have an object fall from rest at a height, is its final velocity a positive or negative value? Likewise, if I throw an object in the air, is its final velocity when it hits the ground positive or negative? Basically, I want to know what is the general rule of thumb for determining the direction of v? Thanks.
