Which of these velocity vs Which of these velocity vs. time graphs above represent an object with decreasing speed? Which of these velocity vs. time graphs above represent an object accelerating and reaching terminal velocity?

A LEVEL PHYSICS Year 1 Motion Graphs A* A B C B/C Target A/A* Target EP AEP C B A A* I can describe the difference between a distance-time graph and a displacement-time graph (grade d) I can determine acceleration and displacement from a velocity time graph (grade b) I know the link between distance/time, velocity/time and acceleration/time graphs (grade a).

Distance-time graph The displacement time graph opposite shows a ball being thrown vertically and falling. Sketch the information in a distance-time graph.

Quick Question A swimmer swims 100m from one end of the pool at a constant speed of 1.2 ms-1 then swims back at a constant speed returning to the starting point 210s after starting. Calculate the time taken for the first ‘length’ and the return length. Sketch a) displacement-time graph b) distance time graph c) velocity-time graph

Velocity-time graphs Assign +ve as one direction and –ve as the other direction Make up a story to fit the adjacent graph Draw a velocity-time graph for the ball being thrown vertically

Quick Question 2 A motorcyclist travelling on a straight road at a constant speed of 8.8 ms-1 passes a cyclist travelling in the same direction at 2.2 ms-1. After 200 s the motorcyclist stops. Calculate how long the motorcyclist has to wait for the cyclist to catch up. On the same axes, sketch a velocity-time graph for both objects
