What is the centripetal force? What is centripetal force

When an object moves in a curve, it must be subjected to an external force that is not in the same straight line as the direction of velocity.

Uniform circular motion is a curvilinear motion, and an object that is moving in a uniform circular motion must also be affected by an external force that is not in the same line as the direction of velocity. This combined external force is the centripetal force.

The centripetal force is directed towards the center of the circle, while the direction of the object's motion is in the tangential direction, so the direction of the centripetal force is always perpendicular to the direction of the object's motion. The object is not subjected to force in the direction of motion, there is no acceleration in this direction, and the magnitude of the velocity does not change, so the action of the centripetal force is only to change the direction of the velocity.

1.Experiments were carried out with steel and aluminum balls of different masses so that the radius r and angular velocity of the two balls were the same. It can be seen that the magnitude of the centripetal force is related to the mass, and the greater the mass, the greater the centripetal force required.

2.Experiment with two balls of the same mass instead, keeping them moving at the same radius. It can be seen that the magnitude of the centripetal force is related to the speed of rotation, and the greater the angular velocity, the greater the centripetal force required.

3.Two balls of the same mass were still used for the experiment, and the angular velocity of the balls was kept the same. It can be seen that the magnitude of the centripetal force is related to the radius of motion of the ball, and the larger the radius of motion, the greater the centripetal force required.

Experiments show that the magnitude of the centripetal force is related to the mass m, the circumferential radius r and the angular velocity of the object. It can be demonstrated that the magnitude of the centripetal force required for uniform circular motion is f mr 2

An object in circular motion, under the action of the centripetal force f, must produce an acceleration, and the direction of this acceleration is the same as the direction of the centripetal force, always pointing to the center of the circle, which is called centripetal acceleration. For a definite uniform circular motion, the magnitude of m, r, and v are constant, so the magnitude of the centripetal force and centripetal acceleration remains the same, but the direction of the centripetal force and centripetal acceleration is always changing. Uniform circular motion is a variable velocity motion in which the direction of the instantaneous acceleration vector is constantly changing.

The centripetal force is the combined force directed towards the center of the circle (center of curvature) when the object moves along a circumferential or curvilinear orbit, and is named after the effect. This effect can be provided by elastic force, gravity, etc., or by the resultant force of several forces or their components.

The centripetal force is the force required to make the particle (or object) move in a curvilinear direction to the center of curvature (which is the center of the circle when it moves in a circle). The term centripetal force can be divided into centripetal force in the physical sense and centripetal force in the sense of mass cohesion from two different perspectives.

In classical mechanics, the centripetal force is the resultant external force that directs an object towards the center of curvature of the circle when it moves along a circumferential or curvilinear track. 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.

Because circular motion is a curvilinear motion, an object in circular motion is also subjected to a resultant force that is different from the direction of its velocity. For an object in a circular motion, the centripetal force is a pulling force whose direction keeps changing as the object moves in a circular orbit. This tensile force points to the center of the circumference along the radius of the circumference, hence the name centripetal force.

The centripetal force is directed towards the circumferential center, and the object controlled by the centripetal force moves in the direction of the tangent, so the centripetal force must be perpendicular to the direction of motion of the controlled object, producing only acceleration in the direction of the normal of velocity. Therefore the centripetal force only changes the direction of motion of the controlled object and does not change the rate of motion, even in non-uniform circular motion. In non-uniform circular motion, the tangential acceleration that changes the rate of motion is not generated by the centripetal force.

If you are a junior high school or high school student: centripetal force is a force classified according to the effect, all objects that do curvilinear motion must be subjected to external forces (you must know this), curvilinear motion must exist in the circle corresponding to each short arc, does the circle have a center of the circle, the force mentioned above to decompose to the position of the center of the circle can be called centripetal force.

The force required to make a particle (or object) move in a curvilinear motion toward the center of curvature (which is the center of the circle in circular motion).

Centripetal force is an abstract concept, not a concrete scientific concept. The centripetal force can be any kind of force such as tensile force, elastic force, gravity force, frictional force, etc., or it can be the resultant force or component force of several forces.

For example, when a ball is pulled with a rope in a uniform circular motion, the pulling force of the rope is like a centripetal force. When the planets revolve around the Sun, the cohesion is the centripetal force. When a car turns, the resultant force of gravity and supporting force is the centripetal force.

The centripetal force is in the opposite direction to the centrifugal force.

When the centripetal force is greater than the centrifugal force, the curvature increases;

When the centripetal force is less than the centrifugal force, the curvature decreases;

When the centripetal force is equal to the centrifugal force, the curvature does not change.

A centripetal force is a force that refers to the direction of an object toward the center of a circle as it moves in a circular motion. In circular motion, the object moves in a curve along the trajectory of the circular motion, and needs to be subjected to a force in the direction of the center of the circle to maintain its trajectory.

The magnitude of the centripetal force is related to the mass of the object, the speed of motion, and the curvature of the trajectory. According to Newton's second law, the magnitude of the centripetal force band experienced by an object is equal to the product of the mass of the object and the centripetal acceleration, i.e., f = mv r, where f is the centripetal force, m is the mass of the object, v is the velocity of the object, and r is the radius of curvature of the trajectory.

Centripetal forces play an important role in many physics applications, such as when a bicycle is turning, where the friction of the wheels against the ground provides a centripetal force that keeps the bike on a curved trajectory. In addition, centripetal force is also involved in astrophysics, astronautics, engineering, and other fields.

The term centripetal force is an abstract concept, not a concrete scientific concept. The centripetal force can be any kind of force such as tension, elasticity, gravity, friction, etc., or it can be the resultant force or component force of several forces.

For example, when pulling a ball with a rope in a uniform circular motion, the pulling force of the rope is a centripetal force. When the planets revolve around the Sun, the cohesion is the centripetal force. When a car turns, the resultant force of gravity and supporting force is the centripetal force.

The centripetal force is in the opposite direction to the centrifugal force.

When the centripetal force is greater than the centrifugal force, the curvature increases;

When the centripetal force is less than the centrifugal force, the curvature decreases;

When the centripetal force is equal to the centrifugal force, the curvature does not change.

Explanation of centripetal force [centripetal force] The force that confines a particle of matter on a curved path and acts towards the center of curvature of the inward path to produce centripetal acceleration (e.g. using the force used by the outer rail on the outer wheel flange to prevent the railway train from leaving the curved track) Explained in detail (1).Physics noun . The force that causes the object to move along the circumference or other curve, perpendicular to the direction of velocity, toward the center of the circle.

2).It is a metaphor for the cohesive and smoldering force of people around a certain center. Guo Moruo, "Rooster Collection: Unite and Unite as One Creation Competition" :

All of them have centripetal force and wisdom and, together with the people of the whole country, have participated in various social reform movements. Ke Ling, "Selected Essays of A Ying": At the same time, Comrade A Ying also set up a "journalism course" at the Shanghai College of Law and Political Science, with the obvious intention of strengthening the centripetal force and cultivating reserve forces.
