Describe what is happening to the velocity if an object moves with an acceleration of -5 m/s/s?
the velocity decreases by 5 m/s every second
If a baseball is thrown into the air, is the displacement positive or negative when the velocity is zero?
velocity is zero at the peak of the path (parabolic curve), at this point displacement is positive
How do you decide which kinematic equation to use?
use the equation that does not include the variable for which you have no information
