Topics in Motion in a Straight Line

1

Basic Concepts of Motion

  • Motion is the change in position of an object with respect to time
  • An object is considered a point object when its size is much smaller than the distance it travels
  • Position is specified with reference to a chosen origin - positive to the right, negative to the left
2

Velocity and Speed

  • Speed is distance traveled per unit time (scalar quantity)
  • Velocity is displacement per unit time (vector quantity)
  • Average velocity can be zero even when average speed is not zero
3

Acceleration

  • Acceleration is the rate of change of velocity with respect to time
  • Can result from change in speed, direction, or both
  • Can be positive, negative, or zero
4

Kinematic Equations of Motion

  • These equations apply only to uniformly accelerated motion
  • Connect five quantities: initial velocity (v₀), final velocity (v), acceleration (a), time (t), and displacement (x)
  • Any three known quantities can be used to find the other two
