level questions: Velocity Time Graphs
| Question | Answer |
|---|---|
| What is a Velocity time Graph used for? | It is used for finding Acceleration |
| What are the properties of a Velocity time graph | Gradient = Acceleration Flat sections = Steady Velocity Steeper graphs = Greater Acceleration Uphill sections = Acceleration Downhill sections = Deceleration Curve = Changing Acceleration Area underneath the line = Distance travelled |
| How to find out Acceleration? | You do the Change in Y axis ---------------------------- Again in two points. [eg 2 s -6 s] Change in X axis |
| How to find out Distance? | First count all the squares underneath the graph OR just divide the graph into Triangles and Squares and then find out the area Then you find how much distance is in one square by looking at the axis If Time goes up by 1 every square and Velocity goes up 0.2, One square = 0.2 meters. Then do: Total numbers of squares x 0.2 And you have Distance |
