Topics in Motion in one Dimension

1

1. Scalar and Vector Quantities

  • Scalar quantities have only magnitude.
  • Vector quantities have magnitude and direction.
  • Negative sign with a vector means opposite direction.
2

2. Rest, Motion, Distance and Displacement

  • A body is at rest if it does not change its position with respect to immediate surroundings.
  • A body is in motion if it changes its position with respect to immediate surroundings.
  • Distance is the total length of the path travelled.
3

3. Speed and Velocity

  • Speed tells how fast a body is moving.
  • Speed is a scalar quantity.
  • Velocity tells both speed and direction of motion.
4

4. Acceleration, Retardation and g

  • Acceleration is the rate of change of velocity with time.
  • Acceleration is a vector quantity.
  • Retardation is negative acceleration.
