Just a couple of questions I'm banging my head on. Any help would be great!
1. Does your accelration have to be negative when you are slowing down?
If I started in a negative direction back towards my initial frame of reference,
accleration would be positive? But isn't that still speeding up?
2. It is a velocity time graph. I'll explain the best I can. It wants to know which is accelrating faster. It is showing 2 graphs. Graph A is a positive velocity with a positive accleration and it has a small slope so all of this is slowly happening. Graph B is positive velocity with a negative accelration and the slope is larger so it is quickly happening.
So when they ask this does it matter if its acclerating or deaccelerating?
