Velocity and acceleration are vector quantities, which means that, in addition to their magnitude, one needs to indicate their orientation to fully describe them. Knowing that the particle acceleration is the rate of change of its velocity, describe what happens to the velocity vector when: a) Velocity and acceleration vectors are in the same direction. b) Velocity and acceleration vectors are in opposite directions. c) Velocity and acceleration vectors are perpendicular. d) Velocity and acceleration vectors form an acute angle. e) Velocity and acceleration vectors form an obtuse angle.
