Earth's Gravitational Field

Question

Answer

Gravity is a force of __________ that exists between any two masses.

What is the force of attraction between our mass and the Earth's (or some other heavenly body)?

What are the three classical vector force fields?

What does the field vector g also represent due to Newton's Second Law of Motion?

What equation represents the Law of Universal Gravitation? (m1=larger object's mass, m2=smaller object's mass, r1=larger objects radius)

What acceleration due to gravity measured in?

What are the three main factors that determine the value of g on Earth? (The first part has three subfactors in it, addressed below)

What are the three factors that effect gravity that purely depend on the location on the Earth's surface?

What is the equation for calculating gravity?

What does Newton's Second Law of Motion state (equation)?

What can be defined as the energy required to move a mass to a specific point within a gravitational field?

This is calculated using what equation? (Let ^ be equal to Ep)

By assuming the object is being moved to a point in a gravitational field where the zero level is at infinite, what must the value of Ep always be?

What equation calculates the Ep of any two objects (m1 is mass of object 1, m2 and object 2 also, r is the distance between them)

What is the three significant figure value for the constant G used in the above equations? (Scientific Notation is used)
