Why you feel pressed back into the seat of a car when it accelerates.

ps.. its based on Newton's inertia, i think. I don't understand this,and i have no idea what this is about...........NO IDEA.............

As you travel over the top of the loop the loop, you observe the world from an inverted perspective. The sky is below you and the ground is above you. If you were to take a coin out of your pocket and release it, you would see it fall toward your seat. From that observation, and the feeling of being pressed into your seat, you might think that gravity is suddenly pulling you toward the sky. It isn't. Gravity is still pulling you toward the ground, but you are in a car that is accelerating rapidly toward the ground. As a result, the car is having to push you toward the ground with a force on the seat of your pants. You feel pressed into your seat because the car is pushing you downward hard. When you release the coin, it seems to fall toward the sky, but it's really just falling more slowly than you are. With the car pushing you downward, you're accelerating toward the ground faster than the coin and you overtake it on the way down. It drifts toward the seat of the car because the car seat accelerates toward it. As you can see, the only forces around are the force of gravity and support forces from the car. There is no outward or upward force here. The fictitious force is truly fictional; a way of talking about the strange pull you feel toward the outside of the loop.

Than u im getting it now i don't need more answers................

Don, that has nothing to do with it. If you don't know, keep quiet please, you do harm to kids wanting to learn the truth.

You feel the seat on your back....you must be accelearting and the seat is pushing you with a force of Force=yourmass*caracceleration.
Yes, you have inertia, and as newton stated, it takes a force to change motion, your motion.

When you feel pressed back into the seat of a car when it accelerates, it is because of Newton's first law of motion, often referred to as the law of inertia. Inertia is the tendency of a body to resist changes in its state of motion.

In the context of a car accelerating, your body naturally tends to maintain its state of rest or uniform motion. When the car suddenly accelerates, your body initially resists the change in its motion and wants to remain at rest. However, the car is exerting a force on your body, pushing it forward.

This force causes your body to accelerate in the same direction as the car. But because your body naturally wants to stay at rest, the seat of the car exerts an equal and opposite force on you, effectively "pushing" you backwards into the seat.

To understand this concept more comprehensively, you could perform a simple thought experiment: imagine sitting in a car that is at rest but suddenly starts moving forward. Since you were initially at rest, your body would want to remain at rest. Due to inertia, you would feel pressed back into the seat as the car accelerates.

If you still find it difficult to grasp the concept, you can try conducting a small experiment. Sit in a rolling office chair and ask a friend to push you gently from behind. Notice how you feel pressed forward into the chair as it resists the change in motion. This experiment helps visualize the application of Newton's first law.

In summary, you feel pressed back into the seat of a car when it accelerates because of Newton's first law of motion, which states that objects at rest tend to stay at rest and objects in motion tend to stay in motion unless acted upon by an external force (such as the force exerted by the car).
