In short: the tires. (friction)
The force changes a few times to get there though.
(gasoline -> chemical reaction -> pressure -> linear kinetic -> rotational kinetic)

Explain differences between contact and noncontact?
A non-contact force is any force applied to an object by another body that is not in direct contact with itexample:A human body's weight is a non-contact force exerted by the Earth on their massa contact force is a force between two objects (or an object and a surface) that are in contact with each other.exampleAn example of contact force commonly encountered in college-level physics is the force between two masses A and B which are lying next to each other and a force F
What is the formula for finding the force exerted by an object?
In physics, Force is what changes or tends to change a state of rest or motion in an object. Force causes objects to accelerate, add to the object's overall pressure, or change direction. Force is measured in Newtons (N). According to Newton's Second Law of Motion, the formula for finding force is: : F = ma where F is the force,m is the mass of an object,and a is the acceleration of the object. If one sets a to the standard gravity g, then another formula can be found: : W = mg where W is the weight of an object,m is the mass of an object,and g is the acceleration due to gravity at sea level. It is about 9.8m / s2. Force is a vector, so it has both a magnitude and a direction. Linear force can be found with this formula: F = LD L is the length of the lever arm and D is the distance it has traveled.
When an object is pulling across a level surface at a constant velocity what force is the pulling force equal to?
Friction.
A net force of 6.8 n accelerates a 31 kg scooter across a level parking lot what is the magnitude of the scooters acceleration?
0.22 m/s2
What two things affect the level of an object acceleration?
The force acting upon the object as well as the mass of the object. Both will affect the acceleration of the object.
When a car speeds up does the drag increase or decrease?
as an object accelerates, the amount of drag exerted on it increases. This means that more force is necessary to sustain the same level of acceleration. If that external force is increasing, as in a car or plane, then the object can be accelerated well past its terminal velocity. If, however, the only force being exerted on it is the force of gravity, then eventually the drag will become as great as the static force of gravity, and the object will cease to accelerate.
Do force exist to object at rest?
There CAN be, as long as the force is being counterd by an equal and opposite force.

When an object is pulled on a level surface at a constant velocity what force is the pulling force equal to?
If there is no friction or anything that can impede the movement off the object, then the force is zero. If there is friction, then the force is equal to that of the friction.

What is the object of the prepositional phrase with such force?
The object of the prepositional phrase "with such force" is the noun or pronoun that the phrase is describing or giving more information about. In this case, the object would be the action being performed with a certain level of strength or intensity.
An unknown force pushes an automobile mass 1700 kg The automobile is on level ground and accelerates at a rate of 3 meters per square second What is the magnitude of the force?
Use Newton's Second Law: force = mass x acceleration.
Why does a skate board stay still?
If an object with wheels (or a round object) is on a level grade, and there is no force acting on it, it will not move.
What is the force of gravity on an object know as?
The force of gravity on any object near the surface of the earth and close to sea level is 9.80 meters per second per second.
