Catapults store potential energy by stretching ropes and rubber bands and even by bending and flexing the wooden lever.
Rubber band catapult science project.
Sneak some science into your play time.
I think it will launch 10 ft because i only put 1 rubber band around the the popsicle stick that will be launching the tinfoil ball.
Put hot glue over the topmost popsicle stick away from the rubber banded end.
The bring science home activity build a catapult showed you how to build a miniature catapult out of popsicle sticks and rubber bands.
Only one rubber band will make it looser causing it to launch farther.
Using a rubber band powered catapult you will send ping pong balls flying through the air.
This catapult worked by storing elastic potential energy.
Finally physics to talk about what happens and why when the catapult is activated.
The ideal place to tie the rubber band would be at 1 3 rd of the length of the popsicle sticks.
Science skills are used to test and hypothesize how far the object catapulted will go.
My hypothesis was that it would launch at least 10ft.
Check out more catapult designs here design this easy catapult with craft sticks a spoon and rubbers bands.
Mitch and i have been designing popsicle stick catapults lately and it s been so freakin fun.
What is the science behind rubber band catapult.
For my science fair project i decided to make a catapult.
Potential energy is the store energy where as the kinetic energy is the energy in motion.
The catapult s design makes it easy to measure and repeat how hard the ball is launched and its direction so you can find the right catapult settings to hit the target reliably.
To measure x 0 you will have to measure the length of the rubber band while it is unstretched but flat.
For the rubber band we recommend measuring your own values in case the type of rubber bands shipped with the catapult kit change over time.
The catapult science basically involves some physics and engineering skills to hurl a projectile without the use of an explosive.
Figure 6 shows how to do this.
With this science project you will try your hand at catapult technology.
Push the small container into the glue.
Wait for some time until the glue dries.
Your catapult is now ready.
Catapult uses math and engineering to build the catapult using glue rubber bands and popsicle sticks.
