Question Answer
Distance-Time Graphs The gradient of the line represents an object's SPEED
Steeper the line on a distance-time graph... greater the speed it represents
Speed Equation: Speed(m/s)=distance travelled(m)/time taken(s)
Acceleration Equation: a=v-u/t
The area under the line on a velocity time graph represents the distance travelled in given time The bigger the area, the greater the distance travelled
Velocity-Time Graphs The gradient represents acceleration
If the line on velocity time graph is horizontal... acceleration would equal zero
A car travels 100m in 5s. What is its average speed? 20m/s
what does a horizontal line on a distance time graph represent? A stationary object
What does a horizontal line on a velocity time graph represent? Constant velocity
A car accelerates from rest to 30m/s in 15s. What is its acceleration? 2m/s2
What does the gradient on a distance time graph represent? The speed
What does the gradient on a velocity time graph represent? The acceleration
What does the area under a velocity time graph represent? The distance tarvelled
