What is the difference between a vector and scalar in physics?

Hello!





What is the difference between a vector and scalar in physics?


Can you also please include an example of both?





Thanks!|||Vector has direction (eg velocity, momentum), scalar is just a number (eg speed). So if you are adding two velocities, you need to consider their directions - if they are not lined up, then your answer will be both lower than a sum of the "speeds", and in a different direction.
