Explain, in terms of Newton's laws of motion and gravity, why the planets orbit the sun.?

Answer 1

any body when thrown along the horizontal direction in gravitational field follows a parabolic path
according to newtons 1 law of motion all body continues to move in state of motion(and rest)unless acted by an external opposing force
so when the planets are moving in the gravitational field of the sun it is pulled inwards by the sun and thus it is supposed to travel in a parabolic path but due to the high speed of revolusion it doesnt collide with the sun instead revolves around it this speed doesnt change for a planet in a partcular orbit because of the first law
the speed of revolution should increase with the decrease in radius of the orbit

Answer 2

there is the data publicly accessible, yet once you're fascinated in the define, photograph this: -The regulation of Gravitation states that tension by way of gravity gets better issues capture up with. -Kepler's First regulation states that Orbits are Ellipses. because of the fact of Kepler's First regulation, each element in the orbit is at a diverse distance from the sunlight. this suggests that the linear speed will additionally be diverse at each element. while planets attitude the sunlight, tension will boost and so does centripetal acceleration. Linear speed rises. as a result, the perspective swept would be bigger. while planets get farther, tension decreases and so does acceleration. Linear speed decreases and the perspective swept would be smaller. What makes the factors equivalent is that the line starting to be a member of the planets and the sunlight additionally will boost with distance, making the area (?r²/pi) equivalent.

Answer 3

If you push an object, it will continue on its path until something else redirects it. The planets are little drops of water, circling a drain which is the sun. The planets are moving fast enough to more or less counter the gravitational pull of our star, locking them into a stable orbit. In space, there is not much friction or other forces to disturb the orbits, so they continue on unchecked. In reality, the planets are inching closer and closer to the sun each year, but at such a slow pace we don't need to worry about it.

Answer 4

J. Keppler Explained it. before Newton. He expounded in his three laws.
He basically indicated that motion of planets were elliptical orbits.
For orbital elliptical motional equilibrium to occur angular momentum had to remain constant.

Later Niels Bohr applied the same principles to explain the Simplest atom in the Universe=The Hydogen atom.
Where the angular momentum of the electron is a constant in the Hydrogen atom.
(Me divided by n )x V x 2pi R= h which is equal to a Constant

Answer 5

The planets orbit the sun because of the sun's gravitational pull

Answer 6

Well lets put it simply.

An object in motion tends to stay in motion & in a straight line of motion unless acted upon by an outside force.

The sun is that outside force. It causes their trajectory to bend around it.
