Questions & Step-by-Step Solutions
Which of the following is NOT a fundamental quantity?
Correct Answer: Force
Step 1: Understand what a fundamental quantity is. Fundamental quantities are basic physical quantities that cannot be defined in terms of other quantities. Examples include mass, length, and time.
Step 2: Identify what a derived quantity is. Derived quantities are those that are calculated from fundamental quantities. For example, force is calculated using mass, length, and time.
Step 3: Analyze the options given in the question. Look for the quantity that is not basic and can be derived from others.
Step 4: Recognize that force is calculated using the formula: Force = mass × acceleration. Since it depends on mass and time, it is not a fundamental quantity.
Step 5: Conclude that force is the correct answer to the question, as it is a derived quantity.
