12. You are building a go-cart. You want to know how you can make it go as fast as it can. Explain how you can use both chemistry and physics to help you build your go-cart (5 points). I

Physical measures:  Reduction of internal friction,  high static friction tire system

chemist. : air-fuel ratio as efficient

Explanation:

A go-Kart is a vehicle that can be with a motor or with pedals, which is in contact with the ground.

Physical measures that help increase vehicle speed are:

* Reduction of internal friction, use bearings, with greased joints to reduce friction

* Decreased friction when forward creating an aerodynamic raindrop shape, sharp at the front and with a rapid descent at the rear, but without abrupt cuts to the geometry

* Path difference for air passing through the top and bottom, to create a downward force help lower the car by increasing speed

* A high static friction tire system so you can move faster on surfaces and take turns faster

* A shifting system to have an effective torque either pedal or motor, gear shifting system

From the point of chemist.

* Obtain an air-fuel ratio as efficient as possible to increase the force per unit of fuel.
