The holiday is only telling notke, size, mass, time, perfection, ' temperature for scalar quantities are returned by the add, delete. a ,V and use arrows to represent the size and direction of the .
Scalar quantity is a quantity that tells sizes are perfect, and complete such a massive scalar resultant temperature can be achieved by adding each other. Vector quantity must specify both magnitude and direction, it will have a perfect understanding can be represented by directed arrows above the letters a, v, and use the arrow represents the size and direction.
Scalar quantity is a quantity only tell the size be integrity, such as time, mass, volume อุณหภูมิการหา scalar results do the positive negative.A.V and use arrows instead of the size and direction of .
