the physics of a car

502 views

A car is the main thing people use to get around. But people usually just get in and go, and then hit the brake either at a stop sign or a stop light. Then they hit the gas when that person is able to go. But driving a car has a lot more than just hitting the gas and brake. There is a lot of factors that have to deal with physics involved.

First, there is many forces acting on a car when it is at rest and when it is moving. Some of those forces are the normal force, which is the car itself. Also, there is a force of friction when the tires are in contact with the ground. Then the force of the ground acting back on the car. Next, once you hit the gas and get going you start to have a velocity. The Faster that you go the more your velocity will pick up, and once you start going the same speed you velocity will start to level out to a constant speed. Lastly, there is momentum when driving. When you have a bigger momentum, it will take longer for you to stop and likewise for a smaller momentum. To find these things you can do your own time trails. and then your reference table and plug in the numbers to solve it.
