How do you find the magnitude of a vector?

Anonymous

∙ 13y ago

Updated: 12/14/2022

The magnitude of a vector can be found by taking the square root of each of the vector components squared. For example, if you had the vector 3i+4j, to find the magnitude, you take

sqrt ( 3²+4² )

To get:

sqrt ( 9+16 )

sqrt ( 25 )

= 5

Works the same in 3D or more, just put all the vector components in.

How do you find magnitude in physics?

In physics, magnitude is the size or quantity of a physical property, such as force or velocity. To find the magnitude of a vector quantity, you can use the Pythagorean theorem, which involves squaring the components of the vector, adding them together, and then taking the square root of the sum. This gives you the magnitude of the vector.
