Niels Bohr.
In the Ptolemaic system, the motions of Mercury, Venus, Mars, Jupiter, and Saturn were described with epicycles. These epicycles were small circles that the planets were thought to move in while also orbiting the Earth on larger deferent circles.
Inertia, the tendency of an object to keep moving in a straight line, combines with gravity, the force that pulls objects together, to cause orbiting. The inertia of an object causes it to keep moving forward, while gravity continuously pulls it towards the center of the orbit, creating a balance that results in a circular or elliptical path around another body.
Orbits are established by the combined effects of gravitational attraction and relative velocity. In other words, the moon, like any orbiting body, moves forward (tangent to its orbit) at a speed just sufficient to ensure that as it falls toward the earth due to gravity, it has moved far enough that the two motions combine to keep it at a roughly stable distance from the earth.
Only one force - gravity.

Two motions of the Earth are rotation and revolution. Rotation is Earth's spinning on its axis, causing day and night, while revolution is Earth's orbiting around the sun, creating the changing seasons.
Rotation about its axis gives day and night. Orbiting the sun gives us the year.
The three major motions that the Earth undergos in space are Revolution(Orbit), Rotation, and Precession
Rotation and Revolution.
The earth rotates on its own axis once every 24 hours, similtaneously it is orbiting the sun at one orbit every 365.24 days
In the Ptolemaic system, the motions of Mercury, Venus, Mars, Jupiter, and Saturn were described with epicycles. These epicycles were small circles that the planets were thought to move in while also orbiting the Earth on larger deferent circles.
I think the answer that is probably being looked for is:Spinning (rotating around its own axis)Orbiting (moving in an elliptical path around the sun)
The three motions of Earth are rotation, revolution, and precession. Rotation is Earth spinning on its axis, causing day and night. Revolution is Earth orbiting the Sun, creating the change in seasons. Precession refers to the slow wobbling of Earth's axis over a period of about 26,000 years.
True. Kepler's laws apply to all objects orbiting the sun, even those that had not yet been discovered during his lifetime.
A physicist studies motion. This field of study includes understanding the properties of objects in motion, analyzing the causes of motion, and predicting the behavior of objects based on their motion.
