Have you ever had the experience of sitting in a fast-moving car, whether it is a bus, a taxi, a private car, a subway, a high-speed rail, an airplane, when the vehicle is turning, you will feel a force thrown outward, so that you have to grab the handrail or lean on the seat to avoid being thrown out?Have you ever wondered why this power comes from **, and what impact does it have?
If you are interested in these questions, then you should keep reading this article. I will explain the causes, effects, and significance of this phenomenon from different perspectives such as physics, biology, and psychology. I hope that through this article, you will be able to have a deeper understanding of this phenomenon and also be able to take better care of your body and mind.
First of all, we need to analyze the causes of this phenomenon from the perspective of physics. We all know that when an object is moving in a circle, it is subjected to a centripetal force, which is caused by the tension or gravity between the object and the center of the circle, and its direction is directed towards the object along the center of the circle. The magnitude of this force, which is related to the mass, velocity, and radius of the object, can be used by formulas.
fc=mv2/r
to represent, among them.
Fc is the centripetal force, m
is the mass of the object, v
is the velocity of the object, r
is the radius of the circumference.
So, when we sit in a fast-moving car, when we turn, we do a circular motion with the vehicle, and we are also affected by a centripetal force, which is caused by the friction or support force between us and the vehicle, and its direction is directed towards us along the center of the circle. The magnitude of this force, which is related to our mass, the speed of the vehicle, and the radius of the turn, can be used by the same formula.
fc=mv2/r
to represent, among them.
Fc is the centripetal force, m
is our quality, v
is the speed of the vehicle, r
is the radius of the turn.
However, our body is not a rigid object, our body is composed of many tissues and organs, and there is a certain elasticity and fluidity between them, so when we are subjected to a centripetal force, our body will produce a reaction force, the direction of this force is along the center of the circle that we are pointing to, and the magnitude of this force is related to our mass, the speed of the vehicle and the radius of the turn, which can be used by formula.
fr=−mv2/r
to represent, among them.
fr is the reaction force, m
is our quality, v
is the speed of the vehicle, r
is the radius of the turn, and a minus sign indicates the opposite direction.
This reaction force, which is the force we feel thrown outward, is caused by our body's resistance to the centripetal force, and its magnitude is equal to the magnitude of the centripetal force, but in the opposite direction. This force, also known as centrifugal force, is a virtual force, it is not due to the action of the outside world, but due to the action of the inside of our body, it is an inertial force, it is generated due to our body wanting to maintain the original direction of speed and does not want to change with the direction of the speed of the vehicle.
So, from the point of view of physics, we can conclude that when we sit in a fast-moving car, when turning, we will feel a force thrown outward, this force is due to the action of centrifugal force, it is caused by the resistance of our body to the centripetal force, its magnitude is equal to the magnitude of the centripetal force, but the direction is opposite, its magnitude and our mass, The speed of the vehicle is related to the radius of the turn, it is a virtual force, it is an inertial force, it is generated by our body wanting to maintain the original direction of speed and not wanting to change with the direction of the speed of the vehicle.
Next, we will analyze the effect of this phenomenon from a biological point of view. We all know that our body has a very important system, which is the balance system, which is made up of parts such as our inner ear, eyes, muscles, and nerves, and its role is to allow us to perceive the position and movement of our body, as well as our surroundings, so that we can maintain the stability and coordination of our body.
Well, when we sit in a fast-moving car, when we are turning, our balance system will be greatly affected because our body and the direction of the speed of the vehicle have changed, and our balance system has not adapted to this change, so our balance system will send some wrong signals to our brain, so that our brain thinks that our body and the surrounding environment have an uncoordinated movement, so that we feel a feeling of imbalance, and this feeling is the feeling we feel to throw outward。
This feeling of imbalance can have some undesirable effects on our body and mind, such as:
Our blood pressure and heart rate will increase, our blood vessels will contract, and our blood circulation will be disturbed, which will increase the burden on our heart and also affect the blood supply to our organs, causing our body functions to decline.
Our breathing will speed up, our lungs will expand, and our oxygen consumption will increase, which will increase our breathing burden and will also affect our gas exchange, causing our body to lack oxygen, experiencing symptoms such as dizziness and nausea.
So, from a biological point of view, we can conclude that when we sit in a fast-moving car, when we turn, we will feel a feeling of imbalance, this feeling is due to the imbalance of our balance system, it is caused by the inconsistency of our body and the direction of the speed of the vehicle, it will bring some adverse effects to our body and mind, such as increased blood pressure, faster breathing, muscle tension, Nervous excitation, etc., these effects can reduce our physical and mental health and performance.
