What citterence between vector and sealar quantities
Answers
Explanation:
ScalarVectorMeaningA scalar quantity has only magnitude, but no direction.Vector quantity has both magnitude and direction.QuantitiesEvery scalar quantity is one-dimensional.Vector quantity can be one, two or three-dimensional.ChangeIt changes with the change in their magnitudeIt changes with the change in their direction or magnitude or both.ResolutionScalar quantity cannot be resolved as it has exactly the same value regardless of direction.Vector quantity can be resolved in any direction using the sine or cosine of the adjacent angle.OperationAny mathematical operation carried out among two or more scalar quantities will provide a scalar only. However, if a scalar is operated with a vector then the result will be a vector.The result of mathematical operations between two or more vectors may give either scalar or vector. For example, the dot product of two vectors gives only scalar; while, cross product, summation, or subtraction between two vectors results in a vector.ExpressionThey are denoted by simple alphabets, e.g. V for velocity.They are denoted by boldface letters, e.g. V for velocity or putting an arrowhead over the letter.MeasurementSimpleComplexExampleA car is moving at a speed of 30 Km per hour.A car is moving with a velocity of 30 Km per hour in the East.
