Ball and ramp controlled
study
Group #5
How does the release
distance affect the bounce
distance of a golf ball from
bounce one to bounce two?
Ipredict that the greater
the release distance the
farther the ball will travel
from bounce one to
bounce two
Controlled Variables: Angle of
the ramp, the ball, the height,
the surface the ramp is on.
Manipulated Variable:
Release point, or distance.
Dependent Variable: The
distance from bounce one to
bounce two.
 Carbon Paper
 Googles
 Golf Ball
 Graf Paper
 Lab Report
 Masking Tape
 Meter Tape
 Scott Paper Towel
 16 D Nail
 2 PBC Pipes
Procedures
 Step 1: We drew a plan/ sketch.
 Step 2: Mark gets bucket of material.
 Step 3: Put on googles.
 Step 4: Construct our PBC pipe ramp.
 Step 5: Put nail in 10 cm mark.
 Step 6: Put down paper towel.
 Step 7: Place carbon paper on paper towel.
 Step 8: Drop our first ball.
The greater the height of
the ball was in the PBC
pipe was the more speed
it picked up, and the
farther the distance was
from bounce one to
bounce two.
Question #1
What happens to the bounce distance when
the release distance increases?
Answer #1
The bounce distance increases when the
release distance increases.
Question #2
What is another variable that you would like to
manipulate? Write down a problem statement
for this new experiment to possibly investigate.
Answer #2
How far would a bouncy ball travel from bounce
one to bounce two?
On the 10 centimeter drop the golf ball traveled a
distance of 43 centimeters from bounce one to bounce
two.
• On the 20 centimeter drop the golf ball traveled a
distance of 51 centimeters from bounce one to bounce
two. That is a difference of 8 centimeters from drop 10.
• On the 40 centimeter drop the golf ball traveled a
distance of 75 centimeters from bounce one to bounce
two. That a difference of 24 centimeters from the 20
centimeters drop.

Observations Part 2
 On the 60 centimeter drop, the ball traveled a distance of
94 centimeters. This was a difference of 24 centimeters
from the 40 centimeter drop.
 On the 80 centimeter drop the ball traveled 114
centimeters. A difference of 13 centimeters from the 60
centimeter drop. On the
 85 centimeter drop the ball traveled a distance of 112
centimeters. This was surprisingly less than the 80
centimeter drop.
In conclusion, the greater the release
distance is the greater the ball traveled
from bounce one to bounce two. This
happened because the farther up in the
tube the ball is the more time it has to build
up speed, creating a further bounce
distance.
