Key Topics to Revise

1

Motion and Rest - Basic Concepts

  • Motion is the continuous change in position of an object with respect to time and observer
  • Rest means no change in position with respect to time and observer
  • Motion is relative - same object can be at rest for one observer and in motion for another
2

Types of Motion

  • Rectilinear Motion: Object moves along a straight line (e.g., car on straight road, falling stone)
  • Circular Motion: Object follows a circular path (e.g., hands of clock, merry-go-round)
  • Oscillatory Motion: Object moves to and fro about a fixed position (e.g., pendulum, swing)
3

Distance and Displacement

  • Distance is the total path length covered by an object (scalar quantity)
  • Displacement is the shortest distance between initial and final positions (vector quantity)
  • Distance is always positive and can never be zero if object moves
4

Speed and Velocity

  • Speed is distance covered per unit time (scalar quantity)
  • Velocity is displacement per unit time (vector quantity)
  • Speed is always positive, velocity can be positive or negative
