FAQs on Short Tricks for Revision: Units & Dimensions Video Lecture - Physics Class 11 - NEET

1. What are the basic SI units for length, mass, and time?
Ans. The basic SI units for length is meter (m), mass is kilogram (kg), and time is second (s).
2. What is the difference between scalar and vector quantities?
Ans. Scalar quantities have only magnitude, such as temperature or speed, while vector quantities have both magnitude and direction, such as velocity or force.
3. How do you convert units within the metric system?
Ans. To convert units within the metric system, you can use the prefixes. For example, to convert from meters to kilometers, you divide by 1000. To convert from grams to kilograms, you divide by 1000.
4. What is the relationship between units and dimensions?
Ans. Units are the specific quantities used to measure a physical quantity, while dimensions represent the physical nature of the quantity being measured. For example, length is a dimension and meter is a unit for measuring length.
5. How do you perform dimensional analysis to check the correctness of an equation?
Ans. Dimensional analysis involves checking the dimensions of each term in an equation to ensure they are consistent. Each term should have the same dimensions on both sides of the equation. If the dimensions do not match, then there may be an error in the equation.
