What are the definitions and examples of a vector and a scalar according to the text provided in the image?

Answer

Based on the provided text, the definitions and examples are as follows: 1) A vector is defined as a quantity that possesses both a magnitude (size or quantity) and a specific direction. The text provides 'position' as a primary example of a vector quantity because knowing where something is requires both a distance (magnitude) and a direction from a reference point. 2) A scalar is defined as a quantity that has magnitude but no direction. The text provides 'mass' as a primary example of a scalar quantity, as the mass of an object is a measurement of the amount of matter it contains and does not act in any particular direction.
