The force that attracts a body toward the center of the earth, or toward any other physical body having mass
What is gravity?
100
One takes into a count only the object's matter while the other also takes into account the gravitational force
What is the difference between mass and weight?
200
A particle attracts every other particle in the universe using a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
What is the universal law of gravitation?

Radius
What does the variable m stand for?
200
The region of space surrounding a body in which another body experiences a force of gravitational attraction
What is gravitational field?
200
Through this formula, we know that more force is required to launch a more massive satellite into orbit

What does the variable t stand for?
300
He proposed that gravity is not a force but rather an effect of space itself
Who is Albert Einstein
300

What is mass
400
A radius vector joining any planet to the Sun sweeps out equal areas in equal lengths of time
What is Kepler's Second Law?
400
= (r^2)(F grav)/Gm
What is the formula for gravitational mass
400
The numbers below a variable, for example the e or s below the m, that indicate what mass the variable is reffering to (the earth or the sun)
What is a subscript?
400
This can be used to measure gravitational mass
What is a balance?
400
A measure of an object's resistance to other forces
What is inertial mass
500
The ratio of the squares of the periods of any two planets is equal to the ratio of the cubes of their average distances from the sun
What is Kepler's Third Law?
500
T = 2(Pi){square root of: r^3/(G)(m sun)}
What is the formula for a period of a planet orbiting the sun?
500

What is the difference between G and g?
500
Predicts the deflection of light by massive objects
What is the general theory of relativity?
500
The quantity that measures an object's response to gravitational force
