Question

Consider the following statements A and B and identify the correct answer.
A) A body falling freely under the action of gravity does not have one dimensional motion.
B) A body moving uniformly in one frame may be accelerating in some other frame of reference.

• A. Both A and B are true
• B. A is true but B is false
• C. B is true but A is false
• D. Both A and B are false

Answer 1

Answer: (C)

B is true but A is false

Freely falling body only moves in one direction (towards the ground). Hence, it is a one dimensional motion and statement A is false.
A body with uniform motion in one frame of reference can be accelerating in another frame of reference when the frame of reference itself is accelerating.
