Work Done and Frame of Reference – Rankers Physics

Work Done by Constant and Variable Forces: Practice Problem & Solution

Assertion: Work done by a force depends on frame of reference. Reason: Force and displacement both depend on frame of reference.
Both Assertion and Reason are true and Reason is the correct explanation of Assertion.
Both Assertion and Reason are true but Reason is not correct explanation of Assertion.
Assertion is true but Reason is false.
Assertion and Reason are false.

Short Solution (Best for NEET):

To solve this problem, we apply the core principles of Work Done by Constant and Variable Forces. Understanding the underlying formula is key to arriving at the correct answer below:

Work done depends on the frame of reference because displacement depends on the frame of reference. However, real forces do not depend on the frame of reference. Hence, the Assertion is true but the Reason is false.
