Graphical relationship between acceleration, velocity and displacement

I created the following GeoGebra app to illustrate the relationships between the physical quantities acceleration, velocity and displacement.

1. Modify the acceleration graph using the two green dots. Notice how the velocity and displacement graphs would change.
2. You can set the initial values of velocity and displacement using the orange and red dots respectively.
3. Press “Play” to observe how the object moves. Note: the animation takes place in slow-motion, not in real time.
4. Uncheck any of the graphs to hide them.

Here are some learning activities you can try out.

1. Predict the displacement-time graph, following these steps:
1. Uncheck the displacement-time graph.
2. Move the two dots on the acceleration-time graph to zero acceleration.
3. Move the initial velocity to – 10 m s-1.
4. Predict how the displacement-time graph will look like.
2. Predict/describe the movement of the object.
1. Set the dots for acceleration to remain constant for a period of 4 seconds at – 10 m s-2, initial velocity at 20 m s-1, and initial displacement at 0 m.
2. Predict how the object will move, taking the upward direction as positive.
