Velocity-Time Graphs. A velocity-time graph (or speed-time graph) is a way of visually expressing a journey. We are going to be using velocity-time graphs to find two things, primarily: total distance, and acceleration. There are 5 key skills you need to learn. Make sure you are happy with the following topics before continuing: Areas of shapes
VELOCITY-TIME GRAPHS – PRACTICE QUESTIONS 1. The velocity-time graph below shows the journey of a car. 20 (a) Use the graph to estimate the speed of the car after 30 seconds. (b) Use the graph to find the acceleration of the car between 20 and 40 seconds. 2. The velocity-time graph below shows the run of a sprinter. Time (seconds)
Here is the velocity-time graph of a car for 50 seconds. Work out the average acceleration during the 50 seconds. Give the units of your answer. Estimate the time during the 50 seconds when the instantaneous acceleration = the average acceleration You must show your working on the graph..... (2)..... (2) 6.

Draw a velocity time graph for the following motion. A car brakes at traffic lights, its velocity changes from 9 m/s to rest in 6s. It remains at rest for 14s. It then accelerates to 12 m/s in 8s. Draw a set of axes for a velocity-time graph in your jotter.
velocity Velocity-time graph Question: Consider the motion of the object whose velocity-time graph is given in the diagram. 1. What is the acceleration of the object between times and ? 2. What is the acceleration of the object between times and ? 3. What is the net displacement of the object between times and ? 4.
The graph below shows velocity as a function of time for some unknown object. What can we say about the motion of this object? Plot the corresponding graph of acceleration as a function of time. Plot the corresponding graph of displacement as a function of time.
