Motion

Chapter Overview

This chapter explains the concept of motion, its types, and various parameters such as speed, velocity, acceleration, and displacement. It covers uniform and non-uniform motion, equations of motion, graphical representation, and Newton's laws of motion. The chapter lays the foundation for understanding kinematics.

Important Keywords

  • Motion: Change in the position of an object with time.
  • Rest: When an object does not change its position with respect to time.
  • Speed: Distance traveled per unit time.
  • Velocity: Displacement per unit time with direction.
  • Acceleration: Rate of change of velocity.
  • Uniform Motion: Motion with constant speed in a straight line.
  • Non-Uniform Motion: Motion with changing speed or direction.
  • Displacement: The shortest distance from the initial to the final position.
  • Graphical Representation: Motion depicted using graphs.
