Label this D-T Graph |
|
|
|
How do you measure the gradient? |
Gradient = Vertical / Horizontal |
|
Work out the speed from this D-T Graph |
Speed = Gradient Gradient = V/T Gradient = 500/30 Speed = 16.7m/s |
|
|
What does a flat section of a D-T Graph represent? |
No movement - it's stopped |
|
|
What does the steepness of a D-T Graph represent? |
The steeper the graph the faster its going |
|
|
What does a downhill section of a D-T Graph represent? |
It's going back towards its starting point |
|
|
What does a curved section of a D-T Graph represent? |
Acceleration or Deceleration |
|
|
What does a steepening curved section of a D-T Graph represent? |
Its speeding up - increasing gradient |
|
|
What does a levelling off curved section of a D-T Graph represent? |
Its slowing down - decreasing gradient |
|
Label this V-T Graph |
|
|
How do you calculate the acceleration on this V-T Graph? |
Acceleration = Gradient Gradient = V/H = 30/20 Acceleration = 1.5m/s² |
|
How do you calculate the speed on this V-T Graph? |
The speed at any point Is simply found by reading the value off the velocity axis |
|
How do you calculate the distance between T - 80s and t - 100s from this V-T Graph? |
Distance Travelled = area under the graph Area of shaded bit = height x length Area = 50 x 20 Distance = 1000m |
|
|
What does a flat section of a V-T Graph represent? |
Steady Speed |
|
|
What does the steepness of a section of a V-T Graph represent? |
the steeper the graph, the greater the acceleration or deceleration |
|
|
What does a uphill (/) section of a V-T Graph represent? |
acceleration |
|
|
What does a downhill (\) section of a V-T Graph represent? |
Deceleration |
|
|
What is does a curve on a V-T Graph mean? |
Change in acceleration |
