Overview

Motion is a change in position with time. Rest and motion depend on the observer, so the same object may appear at rest for one observer and in motion for another. The chapter explains how motion is described using distance, displacement, speed, velocity, acceleration, graphs, and equations of motio

Key Concepts

Motion is a continuous change

Motion is a continuous change in the position of an object with respect to an observer. An object can be at rest for one observer and in motion for an

Motion in a straight line

Motion in a straight line is rectilinear motion. Motion along a circular path is circular motion. To and fro motion about a fixed point is oscillatory

Distance is the length of

Distance is the length of the path followed by an object. Displacement is the change in position of the object, which is the shortest distance between

Speed is distance travelled per unit

Speed is distance travelled per unit time. Velocity is displacement per unit time. Speed is a scalar quantity, while velocity is a vector quantity bec

Average speed is total distance covered

Average speed is total distance covered divided by total time taken. Average velocity is total displacement divided by total time taken. Average veloc

Learning Objectives

  • Understand motion and rest as relative concepts
