Physics scalar and vector quantities
نص القصة المصورة
- Hello my fellow friend Anas, I am currently having trouble with vector quantities, can you help me?
- Sure my friend Ahmed, vectors are quantities that depend on magnitude and direction. Like for example, force, when the object is moving towards the left direction, the sign will be negative. If the object is moving towards the right, the sign of the force will be positive.
- AH HA Thank you, now I know about vector quantities, but I also want to know about the math related to vector quantities.
- Very easy my friend, in any mathematical equation, in vector entities, the direction of the object must be regarded, therefore you must put a - or + in front of the numerical value
- Actually here, let my friend Omar explain scalar quantities to you.
- AH HA, now I know all about vector quantities, but I also heard about its polar opposite, Scalar quantities, can you also help me with them?
- In basic terms, scalar quantities are one dimensional entities that only have magnitude and don't have a direction. For example, mass, it has only magnitude but no direction.
