What is the unit of angular momentum?

Last Updated:

What is the unit of angular momentum? While reading a question, first note whether it asks for a definition, SI unit, formula, direction, cause, effect, or practical use. Students should therefore read every qualifier, including words such as “always,” “at infinity,” “in vacuum,” “per unit,” and “directly proportional.” Such words often decide the correct option. Revise the definition, symbol, SI unit, formula, and one everyday example as a single learning set. If the topic involves an equation, identify every symbol and its unit.

Akg·m/s
Bkg·m²/s
CN·m
DJ·s
Correct Answer: kg·m²/sYour Answer: B

Explanation

Identify the chapter, recall the exact definition or equation, check the unit or direction if applicable, and then eliminate choices that contradict it. Angular momentum L = Iω has SI unit kg·m²/s which is equivalent to J·s.

FAQ

SSC CGL Physics FAQs

Common questions and clear answers for this topic.

How many physics questions usually appear in the SSC CGL exam?

Physics typically makes up a small portion of the General Science questions, usually focused on concepts rather than numerical problems.

Which physics topics are most important for SSC CGL?

Basic mechanics, heat, sound and light, and electricity and magnetism are the areas that come up most consistently across previous papers.

Do I need to solve numerical problems for SSC CGL physics?

Rarely. Most questions are conceptual and test everyday understanding rather than calculation skills.

Is NCERT physics enough for SSC CGL preparation?

NCERT textbooks from classes 9 and 10 build a strong enough conceptual base for most of what SSC CGL asks.

How can I make physics concepts easier to remember for SSC CGL?

Connecting concepts to everyday observations, like why a thermos keeps tea warm, makes them far easier to recall than memorizing definitions.
