Know complete kepler's laws of planetary motion in simple and easily | By scientechplus

Hello dear all readers,

Welcome to this new concept, so here in this concept you will come to know about all kepler's law of planetary motion.

So let's start to know the concept,

So first of all we know that the kepler's first law,

The Kepler's first law planetary motion : The kepler's first law state that, the orbit of a planet is an ellipse with the sun at one of the foci or focus.

For understanding this kepler's law of planetary motion, first of all we need to know about, what is ellipse ?

So if we talk about ellipse than this ellipse have two foci or we can say two focus point.

This foci is same measure from the centre of the ellipse.

The longer foci diameter is known as or called as 'major axis'.

And the smaller foci diameter is known as or called as 'minor axis'.

So as like that, at one foci the sun is situated and rest of all planet revolve around the sun in elliptical orbit motion.

The second law of kepler's planetary motion : The second kepler's law state that, the line joining the planet and the sun sweeps equal areas in equal interval of time.

The planet which moving from point A to point B and the planet which move from point C to point D, according as you can see in the above given image, so if we calculate both cover area by the planet is same in equal interval of time.

So let's say if we consider, the planet cover 10 metre square in 2 minutes than so in the coming 2 minutes the planet will also cover only 10 metre square area.

I mean to say that, the planet cover equal area in equal interval of time not equal distance.

So this is only possible because of according to the kepler's suggested statement on, "A planet moves faster when it is closer to the sun and the planet moves slowly when it is farther from the sun".

So you have one question arises in your mind that, how it is possible when planet come closer to the sun it moves faster and when it farther from the sun it become slow ?

So the answer is : It is only because of gravitational pull.

When as planet arrives closer to the sun the gravitation pull become more and when the planet farther from the sun the gravitational pull become less.

The third law of kepler's planetary motion : The kepler's third law state that, the square of it's period of revolution around the sun is directly proportional to the cube of the mean distance of a planet from the sun.

The planet as much as time take to revolve around the sun, so square of that time and this is equal to the cube of it's semi major axis.

So we hope you understand this concept very clearly and nicely.

If you have any query related to this concept than please fell free to ask us.

So we will meet you with next upcoming interesting concept.

Goodbye !!!

Thank you...!!!
