Scientists often make measurements. Suppose that the motion is confined to a 2-dimensional plane. As against this, velocity is a vector quantity which measures both magnitude and direction. The physical quantities they measure fall into two categories: scalars and vectors. A physical quantity, having both magnitude and direction, is referred to as a vector. Speed is a scalar quantity and is given by the formula distance (d) divided by the time (t), or speed = d/t. The position of location 1 is the vector from the origin to that point. B) It is the point on the principal axis through which rays of light parallel to the principal axis pass after reflection or appear to be arising from this point on the principal axis. 7 Velocity Vectors.

Vector Quantity: Definition : A scalar is a quantity which needs only its magnitude for complete expression. For example, 9.8m/s^2 downward or -9.8m/s^2 vertically is an acceleration. A vector is a quantity which needs both magnitude and direction for complete expression. A scalar quantity is a quantity that has magnitude only but no direction, while a vector quantity is a quantity that has both magnitude and direction: Let's go through the choices: Displacement: you can move from one point to another towards east, west, north,....etc. A vector is a large quantity and a scalar is a small quantity. Speed does not have a direction like velocity, which is a vector quantity. Geometrically, it is represented by a … A) mass. A. In one-dimensional, or straight-line, motion, the direction of a vector can be given simply by a plus or minus sign. Scalar and Vector are just two of the many quantities used in physics. The resultant vector is the vector that 'results' from adding two or more vectors together. • Changes of direction result in changes in velocity - even if the speed remains constant (why?) Q. Examples of vectors are: displacement, velocity, acceleration, force and electric field.
