Question

Which of the following statements regarding the nature of physical laws is NOT correct?

• A. All conserved quantities are necessarily scalars
• B. The laws of nature do not change with time
• C. The laws of nature are the same everywhere in the universe
• D. The law of gravitation is the same both on the moon and the earth \bigskip

Hint:

Not all conserved quantities are scalars! Momentum and angular momentum are examples of vector quantities that are conserved in physics. Conservation laws apply to both scalars (like energy) and vectors (like momentum and angular momentum).

Answer 1

The Correct Option is A

The statement that "All conserved quantities are necessarily scalars" is not correct. Conserved quantities can be scalars or vectors depending on the nature of the physical phenomenon. For example, the conservation of linear momentum involves vectors, not scalars. Therefore, option (1) is the correct answer.
