0:57 that scientific principal is simple, it's called potential energy which in equation form is: PE = m X g X h or mass times acceleration of gravity times height. The PE turns to kinetic energy after the car is released from the gates. So at rest with the car on the track and at the gates, a car with more mass towards the back of the car with have more PE than a car of equal mass that has most of the mass in the front of the car. Thanks for the video :)
Nice video series. Helped me and my kids reach victory lane this year 2011! Thanks! 3 big trophies! and a alot of frowning parents at the end which made it kind of a bummer. But We WON!
Nice job Ryan! You hit the high points, although I think sanding the wheels on the inside seems to be pretty important too. I haven't shown this to my son, yet but i will!!
So you are soo wrong about where to put the weights.. and you are missing a step with the wheels.. Back in 1977 and 78 I never lost a single race! Dad met someone on a plane that had a huge computer at their work who figured out the secrets!
@whiterabbit1968 wanna see a kid that totally got into the race and even took it to the next level? check out:
"does weight distribution effect speed"
not only did he learn about cars and physics, he learned how to make/post movies, keywords, power point, email, paypal and a little bit of business.
It'd be cool if people wanted to reinforce the experience with a random dollar here and there, but he's also quite capable of washing the neighbor's cars.
the straight away when putting more weight in the front you have momentum to get your car through the straightaway. the reason is that potential energy in the front turns into kinetic energy therefore sending it through the straight away. i know this because i won a championship like that. i couldnt fine a store within 45 miles in my house so i had to buy them online and i tried different stratigies and this workede the best i have built cars and trucks my self i want to send you a video hth
@mixer529 I'm not sure i follow your logic. How can an object that has more of it's mass at a lower height have more PE. Kinetic energy is transformed PE and keeping with the law of conservation of energy I would think more PE would produce more KE :)
this is a good video but putting waits just in the back dosent give the best outcome. .... say if your car weighs 2.5 oz. you have another 2.5 to work with. what i did with my car is that i put 1.6 oz in the front and .8 oz the reason i leave .1 oz. left is that instead of the wood filler i use bondo witch also weighs a fair amount. the reason of putting more than three tmes the weight in the front is that when your first going down the slope the back weight is used but slows the car down on
thanks...what a great dad to get involved...my hubby doesn't car...he worked more on his car than his boys. this year I did not get him a car...but he still waited to the last minute...they have never won in 6 years...but now I think I can do this myself next year...thanks again!
slick 50 works better than graphifite. coat the nail with slick 50 then wipe off then polish. works like a charm. Frist place last 6 years. Now im board with the hobby. Go get em champ go get get em.
good start... take time to ck other sights on how to polish the axles, wedge shaped body style will give you a faster speed.... many tricks on the Web.. Ck with your Dist/Council for rules on making a car.. They are not all the same.. Have a good Race >))
It is not clear how you put the axle onto the wooden block. Can you elaborate on that point? Do you just use the slots provided, or drill new holes, or use glue or what? Thanks.
95% of the time putting the weight in the back of the car is the way to go, (rear weighted car), but it depends on the design of the track. Next year your car will go even faster if you build it backwards from this year. The longest distance from the end of the car to the axle slot should be the front of the car. (opposite of the picture on the box) That will make the car's CoG even more rearward. Unfortunately, if you make the CoG too far back your car will be unstable. good luck next year!
I like the Wii remote idea. It's awesome. I just asked my son to go through his Hot Wheels cars to see if he could find a design he would like to make for next year. Check out his video on our channel and you can see what he decided on.
My son Ben did most of the work on his car for his first year as a Tiger Cub. He is very proud of what he achieved and so are we.
I would also add to your list of two important steps that polishing the axles is very important. You want a finished wheel to spin 20 to 30 seconds once it is on the car. We had a few hit the 40 second spin time and it really gave Ben the edge.
Make sure you weigh the whole car (body, axles, and wheels)... not just the body. Good luck racing!

8th place out of about 30 cars.. .12 sec behind first.. car weighed in at 4.9 maybe that was my mistake..?

Surprised you didn't mention the technique of making the car tilt on 3 wheels at all times. This is a winning trick that I have used many times.

Thanks for emphasizing the importance of the kid doing as much as he can on the car. I wish all the parents thought the same
