The slope on a distance-time graph represents speed.
- Distance is measured in metres
- Time is measured in seconds
- Speed is measured in metres per second
Speed = distance travelled / time taken
The slope on the line of a velocity-time graph represents accereration.
- Braking reduces the velocity of a vehicle
When the line's slop is zero, the acceleration is zero.
The area under the line on a velocity-time graph represents distance travelled.
- For an object moving at constant speed, the distance-time graph is a straight line.
- To find the slope, draw a triangle under the line .
- The height of the triangle represents the distance travelled
- The base of the triangle represents the time taken
Slope of the line = height of triangle/ base of triangle
