If an object is accelerating, it must therefore:
A. be going faster
B. undergo a change in velocity
C. undergo a change in speed
D. experience a change in the direction of motion
Answer:
by the definition itself, acceleration is rate of change of velocity,
so,if a body undergoes acceleration, velocity changes-which is a vector and depends on direction of motion.
the body will change direction of motion,if acceleration is in the direction opposite to the velocity.
