You can not equate the two.
- Gravity/weight - Air resistance/drag/friction - Centrapetal force
The vehicle accelerates, assuming the engine is in a vehicle.
by the negative force and the positive force
The faster something moves, the more air resistance is created. So as gravity pulls something faster, the air resistance increases as it's speed does, until the forces of air resistance and gravity are equal, making the object move at a steady pace.
Gravity and air resistance (drag) are the two opposing forces acting on the falling body. Gravity causes the object to accelerate (fall faster) while the air resistance causes the object to decelerate (fall slower). At a certain velocity called the terminal velocity these two forces are in balance and there is no change in falling speed.
Examples of non-air resistance would be the force of gravity, the force of friction between two solid surfaces, and electromagnetic forces between charged particles.
It isn't, necessarily. But the force of gravity is constant, whereas the force of air resistance depends on how fast you're moving through the air. So when you begin to fall, gravity is stronger, and it makes you fall faster and faster. But as your speed increases, so does the force of air resistance, and eventually, the force of air resistance builds up to be equal to the force of gravity. At that point, you keeep falling, but your speed doesn't grow any more.
Gravity is a non-contact force that acts at a distance between two objects with mass. Contact forces, such as friction and normal force, require physical contact between objects. Magnetic force, electrical force, and air resistance also act without physical contact between objects.
When air resistance is greater than the force of gravity acting on an object, it will slow down the object's descent. This is because the air resistance force counteracts the force of gravity, reducing the acceleration of the object as it falls.
No, air resistance is not a form of gravity. Air resistance is a type of friction that acts on objects moving through the air, slowing them down. Gravity, on the other hand, is the force of attraction between objects with mass.
Terminal Velocity
"Free fall" means that gravity is the only force acting on a body.
Yes, gravity is the force of attraction that exists between all objects with mass, pulling them toward each other. Inertia, on the other hand, is the resistance of an object to changes in its state of motion. Gravity is a force that acts on objects, while inertia is a property of objects themselves.

Terminal Velocity
The force of gravity is stronger between larger masses, and weaker between smaller masses. That's why there's more force between you and the Earth than there is between you and a bowling ball, for example.
Gravity gets stronger with larger masses. The force of gravity is directly proportional to the mass of the objects involved, meaning that the larger the mass, the stronger the gravitational pull between the objects.
