Universal Gravitation and Satellites Worksheet

law of universal gravitation

• states the force of gravity acts between all objects in the universe, this is related to the mass of objects and the distance they are from one another

• Tendency of an object to resist change in motion

• A force that pulls objects together and is the duct tape of the universe.

• SI unit of force and weight

• will always be the same no matter the distance

• doesn't apply on Earth
