Question

Consider the directions of the velocity and the acceleration vectors of an object in uniform
circular motion.
A. Both vectors point away from the center.
B. The velocity points along the tangent, and the acceleration is zero, since the
speed is constant.
C. The velocity points along the tangent, and the acceleration points away from the
center.
D. The vectors are perpendicular.
E. Both vectors point toward the center

( I think it is B but I am not too sure)

Answer 1

google "uniform circular motion"

look at the diagrams on wikipedia

Answer 2

nope, not B. What about D?
