Any Ideas for this Science Project?

Question

I have to create a vehicle that is propelled by Newton's 3rd Law. "For every action, there is an equal and opposite reaction." Basically, something that makes the car go by being pushed against the wall. I've been thinking like a spring or something, but i think everyone's going to do that. Any ideas?

Answer 1

look at MIT's website for ideas in their engineering department.

***********OH i have an idea. ok, so you know those plastic popper things you would get out of the junk machines at the grocery store? (to turn them inside out and they pop with great force) well,if you were to buy a small plastic ball and cut it in half, it would have the same principle. attach it to the back of a light weight car and sit in front of the wall, and ZOOM!



Haha, i keep thinking of things..

is there any restriction on how the vehicle is propelled? i mean, there's nothing saying you can create a catapult? so the car is thrown instead. even though the catapult is doing to the transporting, the car in the catapult would still be transported... can you tell i miss doing these projects?
do some research on past ideas.

relies upon on what grade you're in yet right it somewhat is a good one. Sleep Deprivation Human matters are maximum suitable yet once you may not get no volunteers rats will do try their information in hand eye coordination concentration and reminiscence You try this by ability of giving hassle-free try to video taping them besides as taking particular notes. then you somewhat began the Sleep Deprivation after 3 days try to video tape and take particular notes of the matters information to preform theses projects after being deprived of sleep be valuable to checklist on your notes the cost of each and every reaction till now hand and after For the reminiscence section a dissimilar decision try it somewhat is exactly an identical a the single given till now hand is maximum suitable and for the concentration have the matters examine a short e book and checklist and be conscious their eye strikes additionally checklist and be conscious which concern do no make it nonetheless the undertaking and the time they failed for hand,eye try use something mushy like a sea coast ball and toss it to them recording and noting velocity reaction and expertise to cacth the ball Make you notes into an attention-grabbing presentation write your findings on index playing cards and place them with the presentation and examine them once you teach the video. it somewhat is relaxing to di and may be able to win.

Answer 3

If it doesn't have to be pushed off the wall, make it ultralight and install a balloon to propel it.

Answer 4

I'll bet everybody will be making mouse trap cars. Hopefully you'll get a more original idea than that.

Answer 5

y dnt u construct like a traffic jam or something you can get stuff to make it with like fakes trees and bushes and stuuf at the hobby lobby

Answer 6

You could use a balloon in a box-shaped car.
