Physics Symbols

What is the Importance of Physics Symbols?

In Physics, different symbols or documentations are utilized to mean various amounts. The indications make the portrayal of the amounts simpler. In this page, probably the most well known physics symbols are referenced. Let us assume that a lady drives her car at a speed of 30 kmph and reaches her hometown in 2 hrs and if she drives at 50 kmph, she reaches in 1.5 hr. So, if we have to represent these units as symbols, how can we do that?

Symbols used for physical quantities are vastly different. Sometimes, the symbol may be the first letter of the physical quantities they represent, like ‘d’, which stands for distance. Other times, they may be completely unrelated to the name of the physical quantities, such as c symbolises the speed of light.
