It depends on what form of racing, the restriction is the rules.

limiting displacement, boost (if even allowed), type of fuel allowed.

The down force package the engineers/crew want to run(depending on the curcuit ). If they require a restrictor plate manditory like super speedways in Nascar. FYI they would easily be running 240-250mph if unrestricted.

Gravity.

There will be friction in various forms. These forms may include among other things: air resistance (hence aerodynamic shape), friction between the tyres and the track surface, as well as internal friction from different parts of the car - engine internals, bearings. Some of this friction is good - like the tyres, others needs to made as frictionless as possible, and lubricants are used to do this.

The shape of the car will create a kind of upside down 'lift', called downforce. This I imagine is to do with the Bernouli (sp) principle (though as far as i know this could be in dispute) among other things.

There will be an element of drag behind the car, 'sucking' it backwards, and again the shape of the car is such that this will be kept to a minimum.

There is also inertia - when the car is going round a corner it will naturally 'want' to go in a straight line. This will be evident by the driver feeling a (ficticious) centrifugal force - he/she will feel like they are being flung to the outside of the car, when in reality they are trying to go in a straight line.

Probably some others but those are the main ones that I can think of just now =)

If you want a constant VELOCITY, then the sum of all forces on the car must be zero. That means that, since there will be a backward force due to friction, the engine must provide a forward force to compensate that.

Some forces which affect the speed of car on track are as follows:- 1.) Friction of air with outer body of car. 2.) Friction b/n tyre and the road. 3.) Gravitational force acting downward.

What affects car speed?

Car speed is primarily affected by the engine power, aerodynamics, weight of the vehicle, rolling resistance of tires, road conditions, and driver's behavior. Engine power determines how fast the car accelerates and maintains speed, while aerodynamics impact drag forces. Weight affects acceleration and the energy needed to overcome inertia, while the road conditions and tire resistance influence friction and traction. Lastly, the driver's behavior, such as how they accelerate, brake, and handle the vehicle, also plays a significant role in influencing car speed.
