Questions and Answers

What is the difference between scalar and vector quantities?

Scalar quantities have magnitude only, while vector quantities have both magnitude and direction.

How would you convert 10 kilometers to meters?

10 kilometers is equal to 10,000 meters.

What is dimensional analysis, and why is it useful?

Dimensional analysis is a mathematical technique used to convert units and check the consistency of equations, ensuring they are dimensionally correct.

What are significant figures, and how do they affect calculations?

Significant figures are the digits in a number that contributing to its precision, and they affect calculations by determining how many digits to report in a result. Signup and view all the answers

Define the difference between scalar and vector quantities and provide an example of each.

Scalar quantities have only magnitude, like temperature (e.g., 30°C), while vector quantities have both magnitude and direction, like velocity (e.g., 50 km/h north). Signup and view all the answers

Explain how dimensional analysis can be used to convert units in a scientific calculation.

Dimensional analysis involves using conversion factors to change one unit into another without altering the value, ensuring consistency in equations. Signup and view all the answers

What is the significance of significant figures in measurements, and how should they be determined?

Significant figures convey the precision of a measurement, and they should include all known digits plus one estimated digit, determined by the measurement's accuracy. Signup and view all the answers

Provide an example of a unit conversion involving length and explain the steps involved.

To convert 5 meters to centimeters, multiply by the conversion factor 100 cm/m to get 500 cm, as there are 100 centimeters in a meter. Signup and view all the answers

How would you utilize dimensional analysis to verify the correctness of a physics formula such as the equation for acceleration?

By ensuring the units on both sides of the equation remain consistent, for example, checking if acceleration (m/s²) equals change in velocity (m/s) divided by time (s). Signup and view all the answers
