Vectors are the physical quantities which have both magnitudes and directions and obey the triangle/parallelogram laws of addition and subtraction. It is specified by giving its magnitude by a number and its direction, e.g. Displacement, acceleration, velocity, momentum, force, etc. A vector is represented by a bold face type and also by an arrow placed over a letter, i.e.
`F, a, b` or `vecF,veca,vecb`.
The length of the line gives the magnitude and the arrowhead gives the direction.
The point P is called head or terminal point and point 0 is called tail or initial point of the vector OP.
Amongst the following quantities, which is not a vector quantity?
Options:
(a) Force
(b) Acceleration
(c) Temperature
(d) Velocity
