A car is driven up a hill at a constant speed Discuss all the forces acting on the car What pushes it up in the hill?

The forces acting on the car include:

1) Weight (mass x gravity) of the car.

2) Normal force between the inclined plane at each tire (perpendicular to the inclined plane).

3) Force of static (rolling) friction acting between the tires and the inclined plane (parallel to the plane and acting against the direction of rotation of the tires).

4) Force exerted by the car on the plane (parallel and opposing friction on the inclined plane).

5) Drag force depending on air resistance and velocity of the car.

The car is allowed to climb the hill because of the static friction opposing the force it is exerting. Without this friction, it would not be able to climb the hill.
