Tip: Squeeze the

the axle plug!
Tip: Build yourself a target goal
or measure which of your friends
can shoot the farthest. Also, try out
different angles of elevation!
Answer:
You built a catapult, which uses force to propel the wooden ball. Without
force, there is no acceleration, or change in speed. The catapult uses a
stretched rubber band to supply the force to the ball. This force gives the
ball an acceleration, which means that it flies away in a high trajectory.
Nevertheless, gravity forces the ball back to the ground. Gravity is the
attraction of the Earth that keeps us on the ground — without which we
would float off into space.
Force is measured in Newton (N) in the metric system and in pounds (lb) in
US conventional system. From the point of launch to the return point, the
ball flies in a curve. If you wish to change this curve, change the firing angle
of the catapult and watch what happens.
