100

This astronomer came up with the law of universal gravitation

Newton

According to Newton , gravity is what?

A force of attraction between two masses

100

What is the theory of gravity that says that gravity is the bending of spacetime

General Relativity

100

This law says that orbits are elliptical, not circular

1st Law

200

Egyptians and Babylonians created what to measure the time according to the sun

Sundial

200

This astronomer had an observatory and tracked the movement of the planets, as well as no nose

Tycho Brahe

200

When there is no air resistance, all objects fall...

At the same rate

200

This is the theory that time runs slower near super massive gravity fields

Time dilation

200

This is the equation we use for the third law

t2=r3

300

What structure was aligned with the solstices and used as a calendar

Stonehenge

300

This astronomer pioneered using telescopes in astronomy

Gallileo

How does the moon affect tides?

It causes the water on earth to be pulled to one side, and the tides occur when the earth rotates into it. 

300

This is the fourth dimension in general relativity

time

This law says that Neptune takes loner to orbit the sun than the earth because it is farther away.
