What is circular motion What is circular motion

Let me tell you about it;

Uniform circular motion refers to circular motion at the same rate, and it is important to make it clear that it is the velocity and not the velocity - because here the magnitude is the same; Secondly, it is important to know that velocity is a vector (with magnitude and direction), so the linear velocity of an object moving in a uniform circular motion must change while the angular velocity (scalar) does not change.

When I explain the force analysis you mentioned in the question supplement, when decomposing the force, because the centripetal force is the effect force, the decomposition should also be based on the actual situation, and it should be divided according to the normal and tangent directions. - A high school 3 student (I hope you can make progress in your studies).

v=rw So the linear velocity is related to the angular velocity One changes and the other must change So it does not exist: Is the circumference of the velocity a certain paper angular velocity or a top of the linear velocity?? problems.

When the circular motion is put in the vertical plane, it is a circular motion with variable speed, because there is a gravitational force, so when it turns to different places, it will be subjected to different external forces, which causes the periodic change of linear velocity and angular velocity, that is, the circular motion of variable speed.

And ah...

The decomposition of the force is determined by the force applied and the force So: no matter how far the ball moves from the bottom of the rod, the support force and the centripetal force provided by the combined force of gravity are the same.

Yes, but with an additional force.

Circular motion: It is the movement of the particle on the circumference with a radius of r with a certain point as the center, that is, the trajectory of the particle is the circular motion when the particle loses the side answer. It is one of the most common curvilinear motions, such as motor rotors, wheels, pulleys, etc., all do circular motion, circular motion is divided into, uniform circular motion and variable speed circular motion, rope or rotating ball in the vertical plane, cone pendulum motion in the vertical plane, in circular motion, the most common and simplest is uniform circular motion, because velocity is a vector, so uniform circular motion actually refers to uniform circular motion.

Examples of circular motion are as follows:

An artificial satellite follows its trajectory, attaches a stone with a rope and swings it in circles, a brawling car turns on the track, and an electron enters a flat vertically.

Circular motion is the sum trajectory of a particle moving on a circumference with a radius of r centered on a certain point, which is called "circular motion".

Variable acceleration curve motion. When an object moves in a uniform circular motion, although the magnitude of the velocity remains the same, the direction of the sharpness of the velocity calendar changes all the time, so the uniform circular motion is a variable velocity motion. And because the magnitude of its centripetal acceleration remains unchanged when it moves in a uniform circular motion, but the direction changes at all times, the uniform circular motion is a variable acceleration motion.

Circular motion in life.

Train corner: actually do circular motion, designed so that the outer rail is slightly higher than the inner rail, with centripetal acceleration!

The car crosses the arched bridge: it can also be regarded as a circular motion, and the support force of the bridge to the car is gravity, and because the pressure of the car on the bridge and the support force of the bridge to the car are a pair of action and reaction forces, the magnitude is equal, so the pressure is also the support force.

The car crosses the concave bridge: it can also be regarded as a circular motion, and the support force of the bridge to the car is gravity, because the pressure of the car on the bridge and the support force of the bridge to the car are a pair of action and reaction forces, so the pressure is also the support force.

Weightlessness in spacecraft: It has been mistaken to say that the reason for the weightlessness of a spacecraft is that it is too far away from the Earth and thus escapes the Earth's gravitational pull. It is precisely because of the gravitational pull of the Earth that it is possible for the spacecraft, along with the rest of the crew, to make a circular motion around the Earth.

The analysis here is for circular orbits only.

Circular motion is a uniform velocity curve motion, because the velocity changes by mv r=ma, and because of the circular motion, it moves in a curve.

The motion of the particle in the circumference with a certain point as the center of the circle and the radius of r, that is, when the particle moves, its trajectory is the movement of the circumferential god and the sail is called "circular motion". It is one of the most common curvilinear movements. For example, the motor turns to hail, wheels, pulleys, etc., all move in a circle.

Circular motion is divided into, uniform circular motion and variable speed circular motion (e.g., rope rod rotating ball in vertical plane, cone pendulum motion in vertical plane). In circular motion, the most common and simplest is uniform circular motion (because velocity is a vector quantity, uniform circular motion actually refers to uniform circular motion).

In physics, circular motion is the rotation of a circle on a circle: a circular path or trajectory. When considering the circular motion of an object, the volume size of the object can be ignored and treated as a mass (except aerodynamically).

Examples of circular motion are: an artificial satellite following its trajectory, a rope attached to a rock and swinging in a circle, a racing car turning on a race track, an electron entering a mean magnetic field perpendicularly, a gear turning in a machine (at any point on its surface and inside), a belt drive, the wheels of a train, and the track at a bend.

Circular motion provides the acceleration required by the moving object with centripetal force. This centripetal force pulls the moving object towards the center point of the circular trajectory. If there is no centripetal force, the object will follow Newton's first law in a straight line by inertia.

Even if the velocity of the object does not change, the direction of the object's velocity is constantly changing. That is, in a uniform circular motion, the linear velocity changes (direction), while the angular velocity does not change.

As the name suggests: a trajectory is the movement of a circle.

A trajectory is the motion of a circle or arc.

Since the two balls are relatively stationary on the club, the centripetal force on the two balls is equal, and the formula F=MRW 2 is used to make a pie with Xianchang: m1r1w 2=m2r2w 2

and r1+r2=l

The larry of the R1=M2L (M1+M2) R2=M1L (M1+M2) rope is T=M1R1W 2=M1M2LW 2 (M1+M2).
