Gravitational Fields Flashcards
1
Q
What is a gravitational field?
A
Area affected by pull of gravitational force.
2
Q
What is the Law of Gravitation?
A
Any two point of masses that attract each other with a force that is directly proportional to the product of their masses and inversely proportional to the square of their seperation.
3
