Question

Why is it often useful to use scientific notation when writing values and measurements in physics?

A) It makes the numbers easier to remember.
B) It is the standard format required for all physics calculations.
C) It allows for more precise and concise representation of very large or very small numbers.
D) It is a tradition in the field of physics.

Answer 1

Scientific notation is used in physics for the precise and concise representation of large or small numbers, simplifying calculations and comprehension.

Step-by-step explanation:

Scientific notation is particularly useful in physics because it allows for a more precise and concise representation of very large or very small numbers. This notation uses a coefficient and a power of ten, which makes calculations and the understanding of physical measurements much more manageable. For instance, the mass of a hydrogen atom or the distance to a star would involve figures with many zeros, which are impractical to use in standard decimal form. Scientific notation simplifies these numbers, so 840,000,000,000,000 becomes 8.40 x 10¹⁴, which is much easier to work with in physics equations.
