Projectile Motion and Hill Shape
In this activity the student will visualize the path of a ball as
it rolls over different shaped hills. In this activity a ball will be
rolled from 3 different heights over three different shaped hills.
- Lay out the roller coaster simulator track on the chalk board.
- Using a piece of chalk trace the path of the track and
mark the starting point of the track.
- Roll the ball down the track. If the ball leaves the track,
trace its path with chalk. Then roll it again to see how it
compares with the drawn line.
- Draw the path the ball takes on the paper. Repeat this process
for every hill and every starting position.
Below are three different starting heights for a hill. For each
starting position rate the hills shape as:
(1) Possible optimum hill. The ball will be in free fall the
longest period of time and the ball would softly be caught at the
(2) Safe hill. The ball stays on the hill but does not remain
in free fall for the maximum amount of time.
(3) Unsafe hill. The ball will leave the track and possibly
hit the other side of the track.
