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.
The laws of planetary motion are attributed to Kepler.
3 laws' of planetary motion
uniform and non uniform motion uniform motion [ equal distance in equal intervals of time is known as uniform motion] non uniform motion [equal distance at unequal intervals of time is known as non uniform motion]
Keplar figured out the laws of planetary motion using Tycho Brahe's data.
They all obey Kepler's 3 laws of planetary motion.
"Non-uniform" motion is "accelerated" 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.
The spinning top has uniform motion.
What is the meaning of uniform accelarated motion?
yes the motion of earth around the sun is uniform
yes, acceleration is constant in uniform circular motion
in uniform motion velocity not changes with time but in non uniform motion velocity changes with time.
