Question

Statement 1 : There can be displacement of an object even in the absence of any force acting on it.
Statement 2 : An object in uniform motion in a straight line shows displacement even when the net force acting on it is zero.

• A. Both statement 1 and statement 2 are true and statement 2 is correct explanation of statement 1
• B. Both statement 1 and statement 2 are true, but statement 2 is not correct explanation of statement 1
• C. Statement 1 is true but statement 2 is false
• D. Statement 1 is false but statement 2 is true

Answer 1

Answer: (A)

Both statement 1 and statement 2 are true and statement 2 is correct explanation of statement 1

Answer is A.

If any body is in the state of rest or in uniform motion, it remains in that state until an external force is applied on it.
So, if a body is initially moving with some constant velocity, it can continue to move with same velocity even if no external force is acting on it.
In fact, the effect of force is to accelerate and not just displace. For example, an object moving straight in space far away from any celestial objects will continue to move forever, although there is no force acting on it. This is due to Newton's first law of motion or law of inertia.
Hence, Both statement 1 and statement 2 are true and statement 2 is correct explanation of statement 1.
