Task 2.1
Balloon rocket experiment
TOPIC
HOW DOES A ROCKET MOVE IN SPACE
INTRODUCTION
Objective: The objective of this experiment is to prove how does a rocket moves in space
therefore by using a balloon (balloon rocket experiment).
Background: This experiment gives a brief background about newton is third law of motion,
which state that every action there is an equal but opposite reaction.
Hypothesis: while the air is released out of the balloon by a force exerted by the balloon in one
direction then it causes the balloon to move in opposite direction by the same force. So as the
balloon rocket fly across the cotton string then this is equal but opposite force caused by the air
out of the balloon. And this can be explained by newton is third law of motion.
As the air is released from the balloon and pushes back. Hence the balloon is propelled forward
by the opposite force like a rocket. which is the gas released from the rocket pushes back.
METERIALS
Rubber balloon size 25 cm, Drink straw, Cotton string 2.4 meter (m), Packaging tape, Iron and
chair, Ruler.
METHODS
The cotton string was measured about 2.4 meter (m). set up the balloon rocket to the string
connected the two chairs along the distance of 2.4 meter. And blew up the balloon more than
one time. Then attached one end of a fixed object. And making sure that not to pop the balloon
while in mouth. After took the balloon and taped it onto the straw, as the balloon rocket in a
starting point. After that the balloon is released to let it to move through the string. And
repeated the same steps three times. Then ensure that not have a constant force for the
balloon.
