Science - Physics
Students will understand the factors determining the strength of gravitational and electric forces.
Relate the strength of the gravitational force to the distance between two objects and the mass of the objects (i.e., Newton’s law of universal gravitation).

How Does Gravity Work?
The gravity formula is explained, along with the difference between Newton's gravity and Einstein's gravity.
Is Gravity a Particle or a Wave?
A question that strikes right at the center of one of the hottest and most challenging research topics in physics, according to resident physicist Kurt Riesselmann.
A collection of physics-related links organized by topic: mechanics, matter, thermodynamics, wave phenomena, electricity and magnetism, modern physics, and more.
A great comparison of thermal, electromagnetic, and gravitational energies.
What is Mass?
The difference between mass and weight is discussed.
Why Do Mass and Distance Affect Gravity?
A nice simple discussion of the topic, along with gravitons and links to questions about gravity in space.
Why Gravity Causes Things to Fall
Movies of a tennis ball falling from different heights (Empire State Bldg., Golden Gate Bridge, etc.) with a brief explanation of the acceleration of gravity.
