Hi,
My name is Michael Burt and I am level 3 physics student (high school), and I have a pretty general question about friction.
There's an old 2000 Toyota Corolla sitting in my backyard, and I was wondering what is the total forward force that the engine must create to move the vehicle, or even just the force threshold.
Some assumptions have to be made of course, involving rust and older parts. But I realize that the main friction is with the tires to the pavement, and moving parts within the vehicle.
The stock mass is listed at 1 095 kg, so I understand one of the forces of friction will be the normal force times the percentage of static friction...
Obviously there is a lot more going on here than just a normal force for friction, so maybe someone could explain to me other sources of friction with the vehicle!
I want to be able to find an electric motor to replace my gasoline engine (but maintain the same driveshaft, transmission and so on), using a variable power supply to act as throttle. And to my understanding, if I can calculate the forward force required to actually move the vehicle, then the wattage (J/s) of an appropriate motor could handle that.
Any advice/loop holes in my plan would be greatly appreciated,
Mike.
