It is the gravitational force.
Mostly gravity and static friction. Friction is a manifestation of the electromagnetic force.
It will stay at rest.
a force acting on an object at rest causese it to move
Inertia guarantees that an object at rest will remain at rest and an object in motion will remain in that same motion, so long as there is no external force acting on that object. Alternately, there could be force acting on it as long as that force adds up to zero.
When an object is at rest, the forces acting upon it are balanced - there are no unbalanced forces.
There are forces acting on the car. They are just equal to the force of the car acting on the force. In example, gravity is acting on the car, but the car is pushing back equally. Therefore, the car doesn't move.

zero net force
Magnitude is 315 N. Direction would be opposite the first force, so they cancel out and leave the body at rest.

There can be forces acting on an object while it is at rest, as long as the forces cancel each out. For example: a block laying on a table feels the force of gravity pulling it down, but the table pushes up with the same force. Therefore, the forces cancel and the object remains at rest.
The weight of the crate is acting downward on the ground and the ground is exerting a force equal to the weight of the crate upward on the crate.
An object at rest or in motion with no force acting upon it.
