Question

Joule second is the unit of:

• A. momentum
• B. angular momentum
• C. work
• D. pressure

Answer 1

Answer: (B)

angular momentum

Answer 2

Angular momentum $=m\upsilon r$ $\text{= kilogram }\\!\\!\times\\!\\!\text{ }\frac{\text{metre}}{\text{second}}\text{ }\\!\\!\times\\!\\!\text{ metre}$ $\text{= kilogram }\\!\\!\times\\!\\!\text{ }\frac{{{\text{(metre)}}^{\text{2}}}\text{ }\\!\\!\times\\!\\!\text{ second}}{\text{second }\\!\\!\times\\!\\!\text{ second}}$ $=\left( kg\times \frac{metre}{{{\sec }^{2}}} \right)\times \sec$ $=joule\times \sec$
