Name the main resistive force that opposes the driving force when a vehicle is moving.

The main resistive force that opposes the driving force when a vehicle is moving is Drag Force/ Air resistance. Air resistance is the frictional force exert by air on the moving body. Greater the velocity of the body, more it will experience air resistance. Air resistance tries to slow down the slow down the speed of the body. The force by engines tries to move it forward and drag force tries to move it in opposite direction. If the force by car engine is greater than the drag force, car will move forward.  

The answer is: Aerodynamic resistance, and Resistance of inertia.

Explanation:

The resistances can be:

Rolling resistance is also known as rolling friction and occurs when the tire rolls on a flat surface in a straight line.

Aerodynamic resistance is the opposite force that air exerts when your car is moving. That is, the force that opposes the advancement of your vehicle through the air.

The resistance of mechanical friction is the resistance due to friction between the engine and transmission parts.

The resistance of the inertia the inertia of your vehicle can also suppose a resistance to the advance.

The resistance due to the slope takes place when you travel in your car uphill.

The answer is: Aerodynamic resistance, and Resistance of inertia.

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .

reserve is the answer
