The path of a tossed ball

When something moves, it passes through many places one after another. All these places together make its trajectory, which can be straight, circular or curved.

In the picture

  1. Starting point: where the ball leaves the hand
  2. Rising part of the path: the ball climbs along a curve
  3. Top of the curve: the highest place the ball reaches
  4. End point: where the ball lands on the grass

Examples

  • A thrown ball draws a curved arch through the air.
  • The tip of a clock’s hand moves along a circular path.
