6 Forces Of A Toy Car

When we were designing what our machine was going to be like, we wanted it to be simple, yet have at least 10 steps and 6 forces. With our design, it will have 12 steps and 6 forces. I am actually really proud of our design. It comes out to be relatively simple, but it gets the job done. Starting with step 1, there is a fan that one of my group members starts by pressing the button on the fan. The fan blows air to get the paper to fly forward away from a toy car that it parked at the top of the race car track ramp. The paper flies forward because of lift force. Next is step 2. The paper rubs against the back of the toy car as it gets blown away. Then, this make the car start rolling. This is contact force. After that comes step 3. The car now

In step 4, the car slams into the ball with contact force that makes it start rolling. On to step 5, the ball increasingly speeds up from positive acceleration as it goes down the ramp because of the force of gravity. Then, there is step 6. Step 6 starts at the exact moment the ball hits the first domino that is standing there waiting. This is contact force that makes all of the dominoes fall one after the other like a chain reaction. Step 7 happens after that. Step 7 is when the last domino hits the button on the tape measure. The tape measure quickly pulls back the extended measuring tape coming out of it. The measuring tape is tied to straw like objects that create a wall to keep the marbles from falling. The measuring tape flies backwards creating tension force on the measuring tape. In step 8, the marbles all drop because the wall was removed from step 7. The reason the marbles actually drop instead of stay floating there in the air is because of the force of gravity. Step 9 is when the marbles land in the bucket. This is contact force. Step 10 is next. There is a platform under that bucket and under that there is a

There are many advantages to a lot of the steps and all of the materials we used. The materials we used were a fan, a piece of paper, a toy car, a race car track, a little ramp, dominoes, tape measure, a marble machine type thing, two buckets, marbles, a spring, a pulley, some string, a balloon, and a little paper flag. All of these things are relatively cheap and easy to get. The only thing that is going to have to be bought for this project is a balloon with helium, and those are inexpensive. Our idea can be built and taken down fairly easily too. In our project we are hoping to make our machine complete its task in 30-40 seconds. This would require precise times when we are doing our “run throughs”. There is a very good advantage that comes from step 6. In step 6, all of the dominoes fall one after the other. Depending on our first time of doing a “run through”, we can then make judgements on how many dominoes to add or subtract from step 6 for the next time doing a “run through” to accurately change the amount of time the machine takes to complete its
