Maximum Height of a Marble Launched from Different Angles
In order to find the maximum height of the marble launched at the wall for various
angles, a marble launcher with a constant launching velocity is placed at a fixed
distance from a wall. The constant launching velocity is determined prior to the
experiment. The obtained experimental value is then discussed and compared to
the theoretical value.
I. INTRODUCTION
A marble launcher is placed one meter away from a wall. The marble launcher is set
to launch the marble at a certain angle. The marble is then launched several times
against the wall and the maximum height for the particular angle is recorded. The angle
is then changed to see which angle can project the marble to the highest height at the
given distance.
The initial velocity of the marble when launched is determined by seeing how far the
marble travels, leveled to the launched height, in the
direction at a certain angle.
II. THE MODEL
The motion of a marble launched from a marble launcher can be described by two
equations.
