Question

Define vector and scalar with example of each. ​

Answer 1

Answer:

1. Vectors - These are those quantities which have both magnitude as well as direction. Example - velocity, displacement.
2. Scalar - These are those quantities which express only magnitude. Example - Speed, distance.

Answer 2

Explanation:

Scalar quantities are defined by a magnitude with no applicable direction. In contrast, vector quantities must have both magnitude and direction of action.

The product of a vector quantity and a scalar quantity will always be a vector quantity. Force results from the product of mass (scalar) and acceleration (vector). Weight is a type of force, generated by the acceleration of gravity.

Voltage is a scalar quantity and can be calculated by the product of current (scalar) and resistance (scalar).

Work is a vector quantity and can be calculated by the product of a force (vector) and displacement (vector).

Velocity is a vector and can be calculated by the quotient of displacement (vector) per unit time (scalar).
