Instructions -
What will happen when the two balls are launched from one end of the track with the
same initial velocity?:
1) will ball #1 on the straight track arrive at the other end first?
2) will ball #2 on the track with the dip arrive at the other end first?
3) will the race be a tie? - both balls reach the other end at the same time?
This is a java version for one of our physics demostration.

Did you get the correct answer?
Press the start button to restart.
- Clicking on the left button within the window will suspend the animation
click it again to resume.
- Click the right mouse button and drag it up and down
in order to change the shape of the lower track.
- Click the more information checkbox in order to display more information
- Shape of the track ( from left to right)
section 1 red curve: one quarter of a circle
tangential component of the gravitation field is the source of the
acceleration.
section 2 blue curve: Trajectory for a
projectile
(with initial velocity when it entering this
region)
So, horizontal component of the velocity is a constant.
section 3 red curve: part of a circle.
The slope for the curves match at the
boundary.
particle will accelerate (as section 1) but
with different acceleration
section 4 blue curve: Trajectory for
projectile similar similar to section 2
section 5 green line: horizontal line.
The velocity is a constant in this region.
- The horizontal component of the velocities are also shown.
