an equal static frictional force from the road /\
common answer is that the engine makes the car go forward but, it is the engine that makes the wheels go around but if the tires are on slick ice or deep mud, they just spin. Friction is also needed. On firm ground, the tires push backwards against the ground because of friction. By Newton's 3rd law, the ground pushes on the tires in the opposite direction, accelerating the car forward.
The seat belt makes an balance forward force because when the car stops you fall forward and the seat belt makes it so the force in your body stays balanced. So it becomes an balanced forward force.
gravitational force
The engine and the force of the tires on the road makes the car go.
The force of gavity on car exerts friction on the wheels and axle that eventually stop the car from exerting forward force.
This is not a force, but your conservation of momentum. For there to be a force, you must have some acceleration, but what you feel is actually your body attempting to continue moving forward until the force of friction and force normal of your seat belt decelerate you.
The neutral position puts a cars transmission out of gear and therefore makes the car roll.
There is no such thing as "force of inertia". The passengers are thrown forward, maintaining their initial motion. This is an application of Newton's First Law, which states that an object in motion stays in motion unless acted upon a force. The force of the car brake is acted upon the car and not on the passengers. This is why the passengers continue to move forward for a second when the car stops.
When forces are balanced, then the object cannot move. Imagine a car on neutral gear. You and your friend are pushing on the car; you are pushing it forward from the back and your friend is pushing it backward from the front. If both you and your friend are applying the same amount of force, then the car isn't going to go anywhere. But if you are applying more force than your friend, the car will move forward at the difference between your force and your friend's force.
centrifugal force
You could write that they helped people to understand the concepts of it and so they decided that if a car gets hit straight on the car will want to move forward but won't so then that force will cause you to fly forward and so with the car safety equipment the force won't pull you forward cause you will have a seat belt on that stops you from flying forward at the speed of the impact.
1. force that moves a car forward is the friction force between the tires and the road (ignoring what is going on mechanically in the car) 2. if the car is travelling at constant velocity, net force is zero - forces pushing car forward are equal to forces pushing car back
If you are behind a car, about to push it forward from a resting position, you will need to exert a force on the car to accelerate it from resting position. While you are pushing against the car, however, there will be a reaction force pushing back at you. In order to produce a large net force against the car without being pushed backward yourself, you need to increase the friction of your feet against the ground...so that the frictional force between your feet and the ground prevents you from sliding backward. The combinations of the frictional force and your force pushing forward against the car will cause the car to move forward. The frictional force of the car being moved from resting position also has to be overcome, of course.
