haretortoise.iwp
The graph shows position vs. time of two objects which we will call a hare (red) and a tortoise (blue). The animals are in a race. The tortoise gets the advantage of a head start 100 m ahead of the hare. The hare runs ten times as fast as the tortoise does. Where and when does the hare catch up to the tortoise? The initial positions and velocities of the animals are given. These can be changed to produce different results. After changing any input, click Reset. Time, position, and separation of the animals are given above the play buttons.
haretortoise2.iwp
Now the tortoise has an acceleration to try to outrun the rabbit. (Note that the axis scales have been changed.) Play the animation to see how the hare won't be able to catch the tortoise. Change the acceleration to 0.5 m/s**2, reset, and run again. Click Show graph. The black line shows the distance between the hare and tortoise as a function of time. Note how it dips to a minimum and then rises without ever reaching zero. What is the greatest acceleration that the tortoise can have and still be caught by the hare? Where and when do their paths intersect?
kingraph2.iwp
Play the animation to display a position vs. time graph of the red dot. The values of position and velocity are given as outputs. Record in your notes a table of positions and velocities at about 6 different times.
roadrage-bk.iwp
This applet models a problem presented by Boris Korsunsky in The Physics Teacher magazine: Two objects approach each other initially with accelerations in the opposite directions as their initial velocities. What is the time interval between successive crossings of the objects? You should solve the problem in general and then use the Animator to test specific cases.
velocity02.iwp
The situation is similar to the last problem but with different initial values. Change the inputs in order to model the motion of an object thrown vertically from the ground at 30 m/s. (What should you input for the acceleration?). Type in values of initial position, initial velocity, and acceleration and run the animation. Remember to click Reset whenever you change an input. Click Show graph to show velocity vs. time and acceleration vs. time graphs.
velocity02b.iwp
The situation is similar to the last problem but with different initial values. Change the inputs in order to model the motion of an object thrown vertically from the ground (initial position of 0 m) at 25 m/s. (What should you input for the acceleration?). Type in values of initial position, initial velocity, and acceleration and run the animation. Remember to click Reset whenever you change an input. Click Show graph to show velocity vs. time and acceleration vs. time graphs.
window01.iwp
These two objects fall from rest under the influence of gravity only. The red object is released at t = 0. The release of the green object is delayed by 1.0 s. Change the height of the window so that one object will appear at the bottom of the window at the same time as the other object appears at the top of the window.
