Another Graph of motion is the Velocity Time Graph. This tells us the velocity of an object and the time taken. From this we acn also deduce the distance travelled and the acceleration of the object.
Reading off a Graph of Motion
- Horizontal line: The object is moving at a constant velocity.
- Positive diagonal line (sloping upwards): The object is accelerating.
- Negative diagonal line (sloping downwards): The object is decelerating.
To determine the distance travelled, we calaculate the area beneath the line on the graph.
To calculate the objects acceleration we use the equation:
- a = y/x
- or Acceleration = Velocity/Time
