Objects that move in a circular motion will have a tendency to move towards the center of the circle

The object in circular motion will be subjected to force, and the resultant force of the force received = the centripetal force of the object in circular motion, then the object will move in a uniform circular motion.

The resultant force of the force experienced is greater than the centripetal force of the object in a circular motion, then the object has a tendency to move towards the center of the circle, that is, centripetal motion.

The resultant force of the force experienced is less than the centripetal force of the object moving in a circular motion, then the object has a tendency to move away from the center of the circle, i.e., centrifugal motion.

There is a centripetal force that moves towards the center of the circle, so there is a force pulling in the direction towards the center of the circle.

There are two forces in a circular motion, one force is directed to the center of the circle, which is the centripetal force, and the other force is along the tangent direction of this point, and the sum of the two forces is along the direction of motion, so that the circular motion can be done. Do you understand?

Hopefully, thank you.

It should be said that objects have a tendency to move away from the center of the circle. The linear velocity of an object is the tangent direction of the circle. If there is no centripetal force, the object will move away from the center of the circle. Only when the centripetal force increases, will the object get closer to the center of the circle.

If the required centripetal force increases, there is a tendency to move away from the center of the circle; (Centrifugal movement).

If the required centripetal force decreases, then there is a tendency to move towards the center of the circle. (centripetal motion).

In mechanical dynamics, there is a virtual Coriolis force in the non-inertial frame at the time of variable acceleration motion, which is far away from the centric motion trend.

Summary. It should be said that it is perpendicular to the instantaneous direction of motion, and the positive direction is that the center of the circle in which the curve is located is pointing towards the object.

If an object does not move in a circular motion, is there still a centripetal force. Is centripetal force only present in circular motion.

No. Objects do curvilinear motion with centripetal force.

The centripetal force is an effect force. If there is no effect, there is no such force.

That is, if the object does not move in a curvilinear way, there is no such force.

This is different from gravity, which is a qualitative force, and gravity is always present regardless of whether it falls or not.

Is it an arbitrary curve and not the arc length of a circle (part of a circle).

Yes, arbitrary curvilinear motion, including arc and circular motion.

The centripetal force is the effect force, so we can't grind it into account when we analyze the force, so when we do the multiple-choice question about the force analysis, all the centripetal force is excluded.

Where does the direction of the centripetal force of any curvilinear motion (not circular motion) be.

and the tangent of the instantaneous direction of motion perpendicular to it.

It should be said that it is perpendicular to the instantaneous direction of motion, and the positive direction is that the center of the circle in which the curve is located is pointing towards the object.

Forgot to consider centrifugal force. The circular motion is done because the centrifugal force cancels out the centripetal force exerted. If the centripetal force caused by gravity is relatively large, the circumference will spiral closer to the center of the circle, causing the two planets to collide.

If the centrifugal force is large, the planet will be thrown out of the galaxy and continue to move in a straight line.

1: The term "centripetal force" is named from the effect produced by the action of this combined external force. This effect can be produced by any force such as elasticity, gravity, friction, etc., or it can be provided by the resultant force or components of several forces.

It's not really a force, it's an effect force.

2: In order to change the direction of the speed of the object, a certain amount of force is required, and when the object is in circular motion, the magnitude of the centripetal force is exactly equal to the required force, so it has no "spare force" to pull the object towards the center of the circle. In fact, if the force given is greater than the required centripetal force, it will indeed pull the object towards the center of the circle, and if the force given is less than the required centripetal force, there will be a partial velocity in the horizontal tangent direction, so that the moving object will move in a curvilinear motion away from the circumferential orbit.

When an object moves in a circular motion, it is subjected to both centripetal and centrifugal forces, which are paired and appear at the same time. Under normal circumstances, the centripetal and centrifugal forces remain balanced, and the radius of motion remains unchanged. When the centrifugal force increases, the equilibrium is broken and the radius of motion increases until a new equilibrium point is reached.

When the centrifugal force decreases, the radius of motion decreases. The spacecraft relies on continuously increasing the circumferential velocity to continuously increase the radius of motion, so as to get rid of the earth's gravity and jump to the next circular motion, which is also called escape velocity.

It will pull the object towards the center of the circle, and if it is not pulled, the object will maintain a uniform linear motion and will move away from the center of the circle.

I remember when I first learned it, I had other forces besides centripetal force to keep him balanced.

No, objects have inertia.

And gravity and other forces!

Centripetal force is required for an object to move in a circular motion. The centripetal component of the resultant external force on the object must be equal to the required centripetal force. This is the condition for an object to move in a circle!

When the tangential component of the resultant external force on the object is equal to zero, the object moves in a uniform circular motion.

The tangential direction of the resultant external force on the object accelerates the circular motion when the direction of the component force is the same as the direction of velocity.

When the tangential direction of the combined external force on the object is opposite to the direction of velocity, it decelerates in a circular motion.

According to f=ma, the object moving in a uniform circular motion must be subjected to a constant direction towards the center of the circle f, so the direction of its acceleration is the same as the direction of the force is also directed to the center of the circle.

Has an initial velocity; It is subjected to a force of constant magnitude, perpendicular to the velocity and therefore directed towards the center of the circle (centripetal force). When an object moves in a uniform circular motion, although the magnitude of the velocity remains the same, the direction of the velocity changes all the time, so the uniform circular motion is a variable velocity motion. And because when it moves in a uniform circular motion, the magnitude of its centripetal acceleration remains unchanged, but the direction changes at all times, so the uniform circular motion is a variable acceleration motion.

"Constant velocity" in the term "uniform circular motion" simply means that the velocity is invariant. The object that is moving in a uniform circular motion still has acceleration, and the acceleration is constantly changing, because the direction of its acceleration is constantly changing, and because its trajectory is circular, so the uniform circular motion is a variable acceleration curve motion. The direction of acceleration in a uniform circular motion is always directed towards the center of the circle.

An object moving in a circular motion with variable speed can always decompose an acceleration directed towards the center of the circle, and we call the acceleration that the direction is pointing towards the center of the circle at all times as centripetal acceleration.

Correction: When the car turns, the frictional force acts along the radius towards the center of the circle (inward), and the frictional force acts as a centripetal force (the centripetal force equals the frictional force).

The direction of velocity always changes, the direction of change in velocity always points to the center of the circle, and the acceleration points to the center of the circle, which requires a force pointing to the center of the circle to change the direction of the speed, which is called figuratively.

Centripetal force. The centripetal force is defined according to the effect of motion, not the force actually experienced by the object, but the resultant force of the force actually experienced by the object (gravitational force, elastic force, frictional force, etc.).

Cars and motorcycles need centripetal force when turning--- that is, the force that points to the center of the circle. Otherwise, you can't turn.

This centripetal force is the frictional force of cars and motorcycles on the ground. The direction of this friction is directed towards the center of the circle.

On the other hand, when a car or motorcycle turns, according to the inertia of the object, it always has the property of maintaining a uniform linear motion, that is, it must move in the direction of the tangent, because there is a tendency to move away from the center of the circle, so it is subjected to friction in the opposite direction - pointing to the center of the circle.

As for the sentence you asked, it doesn't make sense. Say no more. [When the car turns, the frictional force acts outward along the radius, completely replacing the centripetal force. It's that you heard it wrong.

It is false to say that the centripetal force of an object moving in a circular motion is constant.

1. For objects moving in a uniform circular motion, the magnitude of the centripetal force remains unchanged, and the direction changes at all times. 2. For objects moving in a circular motion with variable speed, the magnitude of the centripetal force changes in the jujube, and the direction changes at all times. Therefore, it is wrong to say that the centripetal force of an object in circumferential motion is constant.
