Homework Statement
I need to know if these set of velocities changing correspond to acceleration or
deceleration?
-0.9m/s - +4m/s
+4m/s-4.5m/s
Homework Equations
The Attempt at a Solution
I think that
+4m/s-+5m/s is considered acceleration in the same direction
-5m/s-7m/s is considered acceleration in the negative direction
My chemistry told me that it the first example would be an example of a deceleration then an acceleration due to it becoming zero and then accelerating to +4m/sec and that the same idea applies to the second example.
