Jupiter

It only takes 88 days for Mercury to orbit around the sun. No other planet travels around the sun faster. The planet Venus is so bright in the night sky that you may think it is a star. The Romans thought the planet was so pretty that they named it after a goddess.

Mercury revolves faster around the sun as it has the smallest orbit and it takes 88 days to complete its orbit. No other planet in the solar system travels faster than Mercury.

Answer Expert Verified Jupiter moves faster than neptune in its orbit. It is because jupiter is closer to sun than neptune. The time taken to move on the orbit depends upon the distance from the sun. The length of orbit increases with increasing the distance from the sun and hence the speed also varies accordingly.

Kepler’s Third Law: the squares of the orbital periods of the planets are directly proportional to the cubes of the semi major axes of their orbits. Kepler’s Third Law implies that the period for a planet to orbit the Sun increases rapidly with the radius of its orbit.

It turns out that the constant in Kepler’s Third Law depends on the total mass of the two bodies involved. Thus, the constant in Kepler’s application of his Third Law was, for practical purposes, always the same.

“What goes up must come down.” – Isaac Newton.

Suddenly – boink! -an apple hits him on the head. “Aha!” he shouts, or perhaps, “Eureka!” In a flash he understands that the very same force that brought the apple crashing toward the ground also keeps the moon falling toward the Earth and the Earth falling toward the sun: gravity.

Gravity is most accurately described by the general theory of relativity (proposed by Albert Einstein in 1915), which describes gravity not as a force, but as a consequence of masses moving along geodesic lines in a curved spacetime caused by the uneven distribution of mass.

Einstein denied several times that black holes could form. In 1939 he published a paper that argues that a star collapsing would spin faster and faster, spinning at the speed of light with infinite energy well before the point where it is about to collapse into a Schwarzchild singularity, or black hole.

Newton was the better mathematician. Einstein was the greater conceptual genius. Newton essentially set the parameters for the entire field (even though Galileo is right there with Newton).

A non-contact force is a force which acts on an object without coming physically in contact with it. The most familiar non-contact force is gravity, which confers weight. All four known fundamental interactions are non-contact forces: Gravity, the force of attraction that exists among all bodies that have mass.

Non-contact force occurs due to either attraction or repulsion between two objects such that there is no contact between these objects. There is no field linked with the contact force….Non-contact force.
