 * **MOVING WITH CONSTANT VELOCITY** || MOVING WITH CHANGING VELOCITY ||

1.2 understand and use distance-time graphs DISTANCE-TIME GRAPH: The gradient at a point gives the speed.

1.3 recall and use the relationship between average speed, distance moved and time: SPEED: The distance travelled in unit time. Speed is a scalar. Units can be m/s km/h etc


 * ANSWER THESE FOUR QUESTIONS**



REMEMBER: Formula - Information - Substitute - Calculate - Answer - Unit EG: v= d/t = 300/5 = 60 __ Average speed is 60km/h __
 * CALCULATE THE SPEED OF EACH STRAIGHT SECTION OF THE FOLLOWING D-T GRAPHS: **



SOLUTIONS: 60km/h 1.7m/s 0m/s 5m/s 2m/s 0m/s -2.7m/s 0m/s 20m/s 0m/s -27m/s
