-HOW TO find SPEED from a DISTANCE-TIME GRAPH

the speed of the object is represented by the gradient of the line- to find the gradient, we need to draw a triangle under the line:

The HEIGHT of the triangle shows DISTANCE TRAVELLED.

The BASE shows TIME TAKEN:

  GRADIENT OF THE LINE= HEIGHT OF THE TRIANGLE / BASE OF TRIANGLE      (by doing the equation above,) it shows the objects speed.

IMPORTANT TO KNOW:

  • to find the acceleration/deceleration you only need to find the GRADIENT of the line (going up/down- it might form one triangle- and thats all you need to find)
  • to find the distance you need to find the AREA UNDERNEATH THE LINE  (underneath mostly as a rectangle + triangle)
