distinguish between scalar and vector
Answers
Explanation:
Scalars are quantities that are fully described by a magnitude (or numerical value) alone. Vectors are quantities that are fully described by both a magnitude and a direction.
Answer:
Scalars are quantities that are fully described by a magnitude (or numerical value) alone. Vectors are quantities that are fully described by both a magnitude and a direction.
Explanation:
Meaning - A scalar quantity has only magnitude, but no direction. Vector quantity has both magnitude and direction.
Quantities- Every scalar quantity is one-dimensional. Vector quantity can be one, two or three-dimensional.
Change - scalar changes with the change in their magnitude. Vector changes with the change in their direction or magnitude or both.
Resolution- Scalar 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.
Operation- Any 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.
Expression- Scalar 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.
