- velocity - time graphs
- can be used to find acceleration
- gradient = acceleration
- flat sections represent steady velocity
- the steeper the graph, the greater the acceleration or deceleration
- uphill sections are acceleration
- downhill sections are deceleration
- a curve means changing acceleration
- the area under any section of the graph (or all of it) is equal to the distance travelled in that time interval.
- you can find the acceleration, velocity and distance travelled from a velocity - time graph:
- 1. the acceleration represented between 0s and 2s on the graph is: acceleration = gradient = change in the vertical divided by change in the horizontal = 3 over 2 = 1.5m/s
- 2. the velocity at any time is simply found by reading the value off the velocity axis.
- 3. the distance travelled in any time interval is equal to the area under the graph. for example, the distance travelled between t=8s and t=10s is equal to the shaded area, whcih is 10m (5m/s x 2s)
- can be used to find acceleration
