the proportionality constant in Newton’s law of universal gravitation
gravitational constant
The Coulomb constant
The Planck constant
The speed of light
the model of the solar system where the sun is at the center of the solar system and all the planets orbit around it; this is also called the heliocentric model
Copernican model
Geocentric Model: The model of the solar system where the Earth is at the center of the solar system and all the planets orbit around it.
Ptolemaic Model: The model of the solar system where the planets orbit around the sun and the sun orbits around the Earth.
Tychonic Model: The model of the solar system where the planets orbit around the sun, but the sun and the moon both orbit around the Earth.
the theory that gravitational force results from the bending of spacetime by an object’s mass
Einstein’s theory of general relativity
Gravitational force is caused by the attraction of two objects with a strong magnetic field.
Gravitational force is created by the transfer of energy between two particles.
Gravitational force is generated by the movement of particles through a vacuum.
three laws derived by Johannes Kepler that describe the properties of all orbiting satellites
Kepler’s laws of planetary motion
All orbiting satellites must have a circular orbit.
All orbiting satellites must have a constant speed.
All orbiting satellites must have the same orbital period.
states that gravitational force between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

Ptolemaic model
The heliocentric model, where the sun is at the center and the planets orbit around it.
The heliostatic model, where the planets orbit around the sun and the Earth is stationary.
