Overview

Motion in a plane deals with quantities that need both magnitude and direction, so vectors become essential. Scalars such as mass, distance, time, speed, work, energy, power, charge, current, temperature, potential, specific heat and frequency are fully described by magnitude alone. Vectors such as

Key Concepts

These are physical quantities having only

These are physical quantities having only magnitude and no direction. They obey ordinary algebra for addition, subtraction, multiplication and divisio

These are physical quantities having both

These are physical quantities having both magnitude and direction and obey the triangle law or parallelogram law of vector addition.

A vector quantity with a well

A vector quantity with a well-defined starting point. Its sign reverses when coordinate axes are reversed. Examples include displacement, velocity, ra

A vector quantity described by

A vector quantity described by a plane at least, such as rotation. It is also called a pseudo vector, and its direction is given by the screw rule. Ex

A position vector is drawn from

A position vector is drawn from the origin to the object’s position. Displacement vector is the vector from initial position to final position and equ

Learning Objectives
