Question

An object is dropped from a moving vehicle. Identify which of the following statements is not true?
I. The velocity of the object changes.
II. The acceleration of the object changes.
III. The direction of motion of the object changes

• A. I only
• B. II only
• C. I and III only
• D. II and III only
• E. I, II, and III

Answer 1

The correct option is B II only

When the object is dropped from moving vehicle, the object is in free fall. During the free fall, any object has constant acceleration i.e $g=9.8m/s^2$. Thus, the acceleration of the object does not change. As it has acceleration so velocity will change. Thus, statement II can not be true.
