The Earth's rotation causes the Sun to rise in the east and set in the west every day
The Earth's rotation causes the Sun to rise in the east and set in the west every day.
The Sun's gravity pulls the planets in and makes them orbit it. It's just like how the Eath's gravity makes the Moon orbit the Earth, only on a larger scale.
There are numerous theories of planetary motion. Ptolemaeus (earth in the centre), Copernicus (the sun in the centre, planets orbit around it), Kepler (planet orbits are ellipses) all wrote such theories.
Gravity for the real motion, the Earth's rotation for the apparent motion.

newton's third law
Newton's first law of motion is called the law of inertia. It explains that changes in motion (acceleration) require an unbalanced force. It states that a body at rest remains at rest and a body in motion remains in motion in a straight line at a constant velocity unless acted upon by an unbalanced force.
Newton's third law
Brownian motion. This is random motion of micro particles resultimg from collisions between the particle in question and other particles in the surrounding medium.
first law of motion
Friction opposes motion or, more correctly, relative motion between two bodies in contact.Motion.
Energy of motion is called "kinetic energy".
The "equations of motion" are statements that describe motion. They would not be of much use if the very thing they're used to describe caused them to change. I'll say they don't.
