The planets' orbits are elliptical, not exact circles. Still, that doesn't alter the
answer too much.
Two things combine to give the planets their stable orbits:
1) The velocity of the planet, which, at any moment, is " tangential"
to its orbit. (That's, roughly, "sideways" in ordinary words.)
2) The gravitational attraction of the Sun, which is always directly towards the Sun.
(If you can do the mathematics it becomes clearer.)

∙ 11y ago"Circular motion" means that something moves in a circle. This is applicable when something (the Sun, the Earth, etc.) rotates. It is also applicable, to a good approximation, when planets move around the Sun in ellipses. Many of those elliptical orbits are actually quite close to a circle.

Is acceleration uniform in uniformly circular motion?
yes, acceleration is constant in uniform circular motion
In uniform circular motion quantities are constant?
In uniform circular motion, what quantities are constant?
What is the difference between uniform linear motion an uniform circular motion?
linear is which is on a straight path and circular motion is which has a curved path. *In a uniform linear motion,the velocity is constant and the acceleration is zero.So,uniform linear motion is an unaccelerated motion. *In uniform circular motion the velocity can be variable although the speed is uniform.So,it is an accelerated motion.
When an object does circular motion what is constant?
speed... this is said to be uniform circular motion
Is uniformly accelerated motion uniform motion?
yes, acceleration is constant in uniform circular 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 circular motion?
Circular Motion -a motion along a circular path or the motion of an object in a circular Example -blades of a ceiling fan when the fan is switched on. or The motion of body along the circular path is called circular motion
When an object does circular motion what is constant?
speed... this is said to be uniform circular motion
Is uniform circular motion is accelerated motion?
if an object moves along a circular path, the only change in its velocity is due to the change in the direction of the motion. The motion of the object moving along the circular path is, which is a uniform circular motion, is therefore an accelerated motion:):):):/
Is the motion of earth a uniform circular motion?
yes the motion of earth around the sun is uniform
Is uniformly accelerated motion uniform motion?
yes, acceleration is constant in uniform circular motion
Why uniform circular motion is called accelerated motion?
if an object moves along a circular path, the only change in its velocity is due to the change in the direction of the motion. The motion of the object moving along the circular path is, which is a uniform circular motion, is therefore an accelerated motion:):):):/
The type of motion that's present in circular or curved pathways is called?
Uniform circular motion.
What circular motion is one in which an oblect moves in a circular path at constant speed?
This is called uniform circular motion.
