Activities & Simulations

Activity 1

phet.colorado has created an excellent java applet to describe the motion with respect to the position, displacement and acceleration. Using this we can recor the motion and also can replay the recorded motion.

Activity 2

walter-fendt.de has created the Java applet that shows a car moving with constant acceleration. Using this Java applet we can vary the values of initial position, initital velocity and acceleration. We choose the option "Slow motion." 
  • Three diagrams illustrate the motion of the vehicle
  • Position x versus time t
  • Velocity v versus time t
  • Acceleration a versus time t
