    Car
In summary: Just follow the steps and equations I mentioned and you should be able to calculate the maximum slope your car can move on.

ppl i am jus 14 and tryin to make a car
the amount of physics i no is a bit less
i started calculating
by assuming:-
car weight = 50kg
passenger weight 50 kg
propultion system weight =5okg
total weight =150 kg
speed 20km/h = 5.5m/s
i am taking =5 m/s approx
time taken= 10 sec
acceleration =0.5m/s2
force =150 x 0.5=75 Newton
energy =1875juoles = 1.875kj
power = 187.5 watt
my question is that **"how much slope can it move on??"**
coz i don't no cos tan sin

Formatting and full comprehensive sentences are your friend.

You need to know the thrust at the wheels.

Found from engine torque * gear ratio * rolling radius.
This will give you the max force available at the wheels.

F = mg sin theta

Run for a range of theta, and you can find the max slope you can get up.
or rearrange or theta and work it out with arcsin (I don't know if you will have learned that at 14)

I can't find it for you, I have told you how to find it though.
 

1. Can a 14-year-old really make a car?

Yes, it is possible for a 14-year-old to make a car with the right resources, knowledge, and determination. However, it is important to have adult supervision and support during the process.

2. What problems may a 14-year-old encounter while making a car?

Some common problems that a 14-year-old may encounter while making a car include lack of experience, limited resources, and difficulty understanding complex concepts. It is important to research and plan carefully to avoid these issues and seek guidance when needed.

3. What materials and tools are needed to make a car?

The materials and tools required to make a car may vary depending on the type of car you are trying to make. However, some essential items may include a strong frame, engine, wheels, steering system, and various mechanical and electrical components. It is important to research and plan carefully to ensure you have all the necessary materials and tools before starting the project.

4. How long does it take to make a car?

The time it takes to make a car can vary greatly depending on the complexity of the design, the skills and resources of the builder, and the amount of time dedicated to the project. It could take anywhere from several months to several years to complete a car.

5. Is it safe for a 14-year-old to make a car?

As with any project involving tools and machinery, there are potential risks involved in making a car. It is important for a 14-year-old to have adult supervision and follow safety precautions while working on the car. It is also recommended to seek guidance from experienced adults to ensure the car is built safely and properly.
