Bored at home? Want to enjoy cool science experiments and also learn English? Yala, let's get started! The experiment ahead of you Rocket Car (Physics)
Understanding Newton’s Laws, in particular Newton’s Third Law of
Motion by creating a rocket propulsion car.
Newton’s Third Law of Motion is also called the Action-Reaction
Law. For every force exerted on an object, the object exerts a force equal in
magnitude and opposite in direction.
- Cut a straw into two equal halves
- Use sharp end of wooden skewer to poke hole into one wheel. Slide wheel to other end of skewer.
- Insert skewer into one of the straw halves.
- Poke second wheel onto sharp end of skewer.
- Repeat with another straw, skewer and wheels.
- Glue straws onto bottom of plastic base.
- Connect balloon onto another straw, making sure there are no air leaks when balloon is blown up.
- Glue straw to top of plastic base, with open and pointing out of base area.
- Blow up balloon, pinch straw so air does not escape and place wheels on
List of equipment:
- 4plastic circles.
- 2 wooden skewers.
- Square/rectangle plastic base.
- 2 straws.
- 6 Balloon
- Sticky tape/glue.
Sir Isaac Newton was an English physicist and mathematician. He laid
down the foundations for modern physics as we know them today. In this
experiment we will focus on Newton’s Third Law, which states that for any
force acted upon an object, the object will react with a force equal in strength
but opposite in direction, so that the net force acted is zero.
We use this law when swimming, walking or pushing an object.
Rocket propulsion works in the same way – the object exerts a force greater
than its weight in one direction and is therefore pushed in the opposite
direction, like in a rocket launch.
