representing motion

  • The velocity of an object is its speed in a particular direction.

  • When a body changes its speed and/or direction it is said to experience acceleration.

  • The gradient (slope) of a distance-time graph represents the speed of an object.

  • The gradient of a velocity-time graph represents the acceleration of an object.

  • The distance travelled is equal to the area under a velocity-time graph.
