Gravity Flashcards
Gravity
the force that attracts a body toward the center of the earth, or toward any other physical body having mass. For most purposes Newton’s laws of gravity apply, with minor modifications to take the general theory of relativity into account.
Force
strength or energy as an attribute of physical action or movement.
Law of universal gravitation
Newton’s law of universal gravitation states that any two bodies in the universe attract each other with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
Mass
the majority of.
Weight
a body’s relative mass or the quantity of matter contained by it, giving rise to a downward force; the heaviness of a person or thing.
Inertia
The tendency of an object to resist in motion
Newton’s first law
An object at rest stays at rest
