FREEFALL POSITION AND VELOCITY GRAPHS FREE
Students can explore this computational model of a ball in free fall to What has changed as a result? How do the distance, velocity, and acceleration graphs look now? CURRICULAR USES How do the KE and PE change when you change the mass of the ball? What about the motion of the ball?Īs you press the PROCEED FOR ONE STEP button, change the mass of the ball and then continue. Pay attention to the KE + PE monitor throughout the descent. Watch the relationship between KE and PE as you proceed through the model. How is this related to the Distance vs Time graph? Notice how the distance covered in a step is increasing exponentially. Pay attention to the slopes of the Distance, Velocity, and Acceleration graphs. Observe the trace of the ball as it free falls, are there any patterns? This number can be changed at any time during the free fall of the ball.
MASS-OF-BALL is a slider that ranges from 1-10. (The model will stop once the next second of the ball's descent is below the surface of the Earth.)
Continue to press the PROCEED FOR ONE STEP button until the ball hits the Earth. Look at the graphs to observe the changes in motion and energy of the ball over time. Look at the monitors to see the distance covered in one second and the current values of kinetic and potential energy. Press the PROCEED FOR ONE STEP button to advance the ball by one second downward. Set the mass of a ball using the MASS-OF-BALL slider and press the SETUP button. The ball's distance, velocity, acceleration, kinetic energy, and potential energy at each second are recorded on the plots surrounding the view. The distance covered in a step by the ball is shown below the slider for the mass of the ball. The ball’s position is traced at each second by a red dot in the View. The ball’s motion is shown throughout its descent back onto the Earth, represented by the green patches at the bottom of the view. The user can observe the motion of this model step by step, where each step is one second long (this maps into one tick in NetLogo). The mass of the ball can be varied by a user with the MASS-OF-BALL slider below the SETUP button. The model is initialized with a ball on the top of the view. Finally, the users can also change the mass of the object and observe the resulting changes in the motion and mechanical energy of the object. The model also allows users to explore the conservation of mechanical energy. Users can also observe changes in the mechanical energy of the object as it falls. The model is designed for users to observe changes in motion (displacement, velocity and acceleration) of an object in free fall.
