Question

What conditions imply that we can use classical physics without considering special relativity or quantum mechanics?

a) When dealing with macroscopic objects at low speeds.

b) When the objects are of high mass.

c) When the objects are in a vacuum.

d) When dealing with microscopic particles.

Answer 1

Classical physics is applicable when dealing with macroscopic objects at low speeds. Special relativity and quantum mechanics become relevant in scenarios involving high speeds, small scales, or extreme conditions. So, the correct answer is a) When dealing with macroscopic objects at low speeds.

Step-by-step explanation:

Applicability of Classical Physics: Classical physics, encompassing classical mechanics, is well-suited for describing the behavior of macroscopic objects at low speeds. This includes everyday scenarios involving larger objects moving at typical velocities.

Limitations in Extreme Conditions: When dealing with high speeds approaching the speed of light or microscopic particles, the predictions of classical physics diverge from observed phenomena. In such cases, special relativity and quantum mechanics provide more accurate descriptions.

Transition to Modern Physics: The transition from classical physics to special relativity and quantum mechanics occurs when dealing with extreme conditions, small scales, or high speeds where classical physics formulations are insufficient.

Therefore, the correct answer is a) When dealing with macroscopic objects at low speeds.
