Question 1: Initial Position
Set the initial velocity and the acceleration sliders to zero and try different initial position. Observe the effect on the motion and the motion diagram How does xo affect motion?
Question 2: Initial Velocity vo
Set the initial position and acceleration sliders to zero. Move the initial velocity slider back and forth and observe the changing red velocity arrow. Run and observe the simulation with different positive and negative initial- velocities.
Question 3: Acceleration a
Set the initial position slider to - 48m and the initial velocity to zero. Try different positive accelerations. How does the Change in velocity each second relate to the acceleration?
Question 4: Acceleration and Time
Set the initial position to -48m and the initial velocity to +12m/s. Run and observe the simulation with different negative accelerations starting at -1.0m/s2. (Note the simulation is limited to 12 second duration) What makes the car turn around? Can you predict when that will happen, for a particular acceleration? Test your prediction.
Question 5
Set the initial position to +48m and the initial velocity to zero. Try different negative accelerations. How does the change in velocity each second relate to the acceleration?
Question 6
Set the initial position to +48 and the initial velocity to -12mts. Run and observe the simulation with different negative accelerations starting at 1.0m/s2. (Note the simulation is limited to 12 second duration). What makes the car turn around? Can you predict when that will happen, for a particular acceleration? Test your prediction
