Sophia: Gravitational Force & Objects at Rest

The cat's out of the bag (or off the leash, in this case) regarding the expansion of the universe. In this intriguing episode, the narrator explains that space is expanding, not the objects within it. He also tells how expansion...

Facilitate learning as never before with the first video in a series dealing with physics concepts for your science class. Learners visualize Einstein's field equations and the effect of massive objects in passing light before they...

This lesson explains what happens to the gravitational force for an object at rest. It is 2 of 2 in the series titled "Gravitational Force & Objects at Rest."

Seven problems regarding gravitational pull are presented in this physics drill. Pupils solve for displacement, time, speed, and acceleration. Critical thinking and problem solving skills are both required to complete the assignment. 

[Accessible by TX Educators. Free Registration/Login Required] This resource provides flexible alternate or additional learning activities for students learning about the gravitational attraction between objects of different masses at...

This lesson explains how gravitational force is related to free fall, acceleration due to gravity, and Newton's second law of motion.

The average American will move 12 times, which results in a lot of moving furniture! Class members consider the forces required to move objects with a creative simulation that opens with the forces required to push a filing cabinet....

This portion of video from "The Elegant Universe" series explores the progression of our understanding gravity and general relativity. Historic photos, interviews with professors, and modern computer animations tell the story. This video...

Does size or mass impact gravitational pull? Scholars experiment with force pairs to answer that question. They can change the size, mass, and distance between the objects using an engaging simulatoin. This allows pupils to visualize the...
