Detailed explanation-1: -Velocity and displacement are vector quantities whereas speed and distance are scalar quantities.
Detailed explanation-2: -Explanation: Scalar quantities are defined by a magnitude with no applicable direction. In contrast, vector quantities must have both magnitude and direction of action. Some common scalar quantities are distance, speed, mass, and time.
Detailed explanation-3: -Speed is a scalar quantity because it has no defined direction and only magnitude. Velocity is a vector quantity having both magnitude and a direction.
Detailed explanation-4: -Mass is a scalar quantity and weight is a vector quantity.
Detailed explanation-5: -temperature – eg 10 degrees Celsius (°C) mass – eg 5 kilograms (kg) energy – eg 2, 000 joules (J) distance – eg 19 metres (m) speed – eg 8 metres per second (m/s) density – eg 1, 500 kilograms per metre cubed (kg/m 3)
