The tyres of the race car rubs against the road causing friction and the road gets positively charged and the tyres get negatively charged so the electrons move faster on the tyres alowing the car to mo e fast
No, because force is too weak to overcome friction.
Its velocity is reduced as a result of friction and drag.
Motion and Force test much? Heat
It is clear that frictional force will be parallel to inclined plane and in opposite direction of motion. So it will perform negative work on object rolling down. As a result it will reduce its acceleration, Time taken to travel from one point to other will increase Etc.
There are more than two ways. You might need to choose:Friction wastes energyFriction results in heat energy that can be damaging or dangerous because it can result in fires.Friction can result in wear damage to mechanical components.Mechanical components have to be built stronger to withstand the additional stress that occurs at start-ups due to static friction. (Once a system is in motion it has only dynamic friction to cope with.)Friction gradually denatures lubricants requiring their replacement.
Unbalanced Forces will try to create Motion (Kinetic Energy), balanced Forces do not result in Motion. Gravity, Inertia, and Friction will all try to resist the Motion of the object....unless the Force is in the direction of the Gravitational attraction, then the affect is additive.

As a result of friction, kinetic energy is commonly lost; the result is heat energy.
Friction is the result of materials pushing against each other. Liquids are very dense so they produce greater friction. Also the fluid will want to maintain it direction or static position. So an object moving in any other direct ion will be pushing ( friction) against the fluid.
In a car Friction creates Energy losses that result is a loss of mechanical efficiency, and therefore lower gas mileage. On the positive side friction in the Braking System transform energy of motion into HEAT, allowing the car to stop.

I think heat
Heat.
In school mechanics it does not. The force acting on the car is directly proportional to its mass (its weight adjusted for the incline of the ramp). The acceleration of the car is inversely proportional to this force. The overall result is that the mass of the car does not affect its motion. In more advanced mechanics, where friction and drag are taken into account, things start getting more complicated.
