Displacement and distance tend to be similar in meaning, but are different. For example, time and mass are scalar quantities, in which the numerical value and direction can't be predicted. Without guidance, some physical quantities can be defined just by their numerical value. This is because they do not obey the laws of vector addition. velocity, eg 11 metres per second (m/s) upwards. , Does Wittenberg have a strong Pre-Health professions program? Is it always possible to add any two vectors? Vector - A vector is a quantity that has both a magnitude and a direction. A: A physical quantity cannot be called as a vector if its magnitude is zero. Two vectors are said to be equal when they have equal magnitudes and the same directions and represent the same physical quantity. Suppose you tell a friend on a camping trip that you have discovered a terrific fishing hole 6 km from your tent. You may notice that you can find scalar products are often the products of two vector quantities. The vector quantity is a physical quantity which needs both magnitude and direction to define it. The scalar multiplication of two vectors is calculated using the multiplication of the modulus of both vectors along with the cosine of the angle between them. What is scalar and vector quantity? To qualify as a vector, a quantityhaving magnitude and direction must also obey certain rules of combination. Scalars are numbers with merely a magnitude.
