Velocity-Time Graphs

1. VERY IMPORTANT NOTES

1.1. 1) Gradient = Acceleration

1.2. 2) Flat sections represent steady speed

1.3. 3) The steeper the graph, the greater the acceleration or deceleration

1.4. 4) Uphill sections (/) are acceleration

1.5. 5) Downhill section (\) are deceleration

1.6. 6) The area under any section of the graph is equal to the distance travelled in that time interval

1.7. 7) A curve means changing acceleration

2. Calculating Acceleration, Velocity and Distance from a Velocity-Time Graph

2.1. Acceleration = Gradient = vertical change/horizontal change = 20/20 = 1m/s(squared)

2.2. Distance travelled = area = 20*20 = 400 m
