Topics in Motion in a Straight Line

1

1. Frame of Reference and Nature of Motion

  • A frame of reference is an arbitrary reference system with respect to which position and time coordinates of an event are assigned.
  • An inertial reference frame is one in which Newton's first law correctly describes motion when no net external force acts on a body.
  • A non-inertial reference frame is accelerated or rotating.
2

2. Distance and Displacement

  • Distance is the length of the actual path covered by a body in a time interval.
  • Displacement is the difference between final and initial positions.
  • Distance is a scalar quantity.
3

3. Speed, Velocity, and Acceleration

  • Speed is distance travelled per unit time.
  • Speed is a scalar quantity and can never be negative.
  • Velocity is displacement per unit time.
4

4. Graphs of Motion

  • A time-displacement graph shows how displacement changes with time.
  • For a straight line on a time-displacement graph, the slope gives velocity.
  • A greater slope means greater velocity.
