Why artificial satellite goes around the earth in a perfect circular orbit with constant speed?
An artificial satellite travels in a circular orbit around the Earth due to the balance between gravitational force and its inertia. The gravitational pull from the Earth acts as the centripetal force, keeping the satellite in orbit. If the satellite moves at a constant speed, it maintains a stable trajectory, ensuring that the gravitational force is equal to the required centripetal force. This results in a perfect circular orbit, with no change in speed or altitude as long as external forces, such as atmospheric drag, are negligible.

Why Artificial satellite goes around the earth in perfect oribt with constant speed?
An artificial satellite orbits the Earth in a stable orbit due to the balance between gravitational force and its inertia. The gravitational pull of the Earth continuously pulls the satellite towards it, while the satellite's forward velocity keeps it moving in a curved path. This combination results in a circular or elliptical orbit, where the satellite's speed remains constant in the absence of atmospheric drag or other forces. Thus, it maintains a consistent distance from the Earth and a stable orbit.
What are two kinds of circular motion?
translational motion and rotational motion
Is planetary motion a uniform motion?
Planetary motion almost fits into the category of Uniform Circular Motion. Uniform Circular Motion is an object moving around a circle of constant radius at a constant speed. The planets fill all of these requirements except for the fact that their orbits are slightly elliptical. Their orbital paths are almost perfect circles, but they are so close that for Uniform Circular Motion problems, it is not likely that considering the orbits to be circular will produce an incorrect answer.
What is uniform in uniform circular motion?
The speed of the object in motion, the radius of the curve in which it moves, the force acting on it to keep it moving in a circle, its angular velocity, and its centripetal acceleration, are all constant. Notice that its linear velocity is not constant, because the direction of its motion is always changing. Although I guess you'd have to say that its velocity is constant in polar coordinates, because the radial and tangential components are constant.
What is perigee in relation to shuttle orbit?
Perigee is the point in the orbit that is closest to the earth. Satellite orbits are never perfect circles, they are ellipses, some closer to circular than others. The opposite of perigee is apogee.
Why greek astronomers conclude that the heavens were made up of perfect crystalline spheres moviog at constant speeds?
Greek astronomers believed in the concept of uniform circular motion because they observed the predictable movement of the stars and planets across the sky. They thought that the most perfect shape was a circle and that the heavens, being divine and perfect, must move in circular paths at constant speeds to maintain order and harmony in the universe. This idea of celestial spheres helped them explain the motions of celestial bodies without the need for complex mathematical calculations.
To moves around the sun in nearly circular path?
Any satellite circling another object is considered to be 'orbiting' that object in a circular orbit.Wikipedia made the following statement, under topic, "circular orbit":"In astrodynamics or celestial mechanics a circular orbitis an elliptic orbit with the eccentricity equal to 0."Here, the 'eccentricity' would be referring to the degree to which the orbit moves outside that of forming a perfect cirular path. As a circular path would have no variance from being circular, of course, it has no "eccentricity/ies"

Why did greek astronomers conclude that the heavens were made up of perfect crystalline spheres moving at a constant speed?
Greek astronomers believed in the perfection and order of the universe, influenced by their philosophical beliefs. They thought that circular motion represented perfection, and the movement of celestial bodies in perfect spheres at constant speeds aligned with this notion. Additionally, observations of celestial phenomena like the uniformity of star patterns supported this idea.
What use is the concept of perfect competition in business economics?

Which orbit shown has an eccentricity that is closest to 0?
An orbit with an eccentricity closest to 0 is a nearly circular orbit. In such an orbit, the distance between the orbiting body and the focal point remains relatively constant, resulting in a shape that closely resembles a perfect circle. If multiple orbits are shown, the one that appears most circular has the eccentricity closest to 0.
Will it be correct to say that the car moving in a circular path with constant speed has uniform acceleration?
Well, it depends on the environment, but say we are in the most perfect environment, flat, constant friction, no air resistance, no resistance on the car's internal workings, then yes, but say it was going 30 Km/h, then it would keep accelerating until it reached 30, then it would just keep moving at 30 Km/h
