Fermi Laboratory:how Strong Is the Strong Force?
Use this site to learn about the four forces of nature. Also learn what determines the strength of a force. This question and answer site is a link of the Fermi National Accelerator Laboratory.
TeachEngineering
Teach Engineering: Natural Disasters
Students are introduced to our planet's structure and its dynamic system of natural forces through an examination of the natural hazards of earthquakes, volcanoes, landslides, tsunamis, floods and tornados, as well as avalanches, fires,...
Georgia State University
Georgia State University: Hyper Physics: Gravity
Gravity as a fundamental force is explained and an equation for universal gravitation is given.
Khan Academy
Khan Academy: Particle Systems With Forces
Applying the forces of wind and/or gravity to a particle system so that the system can apply force to all individual particles. In addition, adding a repeller where all the force vectors have a different direction is illustrated.
Khan Academy
Khan Academy: Spring Forces
Creating a simulation of a bob hanging from a spring in a two-dimensional space that responds to other forces in the environment (wind, gravity, etc.)
Exploratorium
Exploratorium: Science Snacks: Take It From the Top
Students defy gravity by stacking blocks in different ways in this exercise. Other projects are linked to this lesson as well.
Exploratorium
Exploratorium: Structures Around the World
How does that bridge stay up? What are the forces acting on that column? This site helps students understand how structures can be built by having them build their own. Also provides images of real structures for kids to compare with...
Khan Academy
Khan Academy: Gravitational Attraction
Applies Newton's concept of gravity to computer graphic programming.
Science and Mathematics Initiative for Learning Enhancement (SMILE)
Smile: Measuring the Gravitational Constant, G
A demonstration/lab idea for determining the numerical value of the universal gravitation constant using a torsion balance.
Physics Classroom
The Physics Classroom: Newton's Law of Universal Gravitation
States the equation of Newton's law of universal gravitation. States the value of G and uses the equation to solve problems.
TeachEngineering
Teach Engineering: Mechanics Mania
Through ten lessons and numerous activities, students explore the natural universal rules engineers and physicists use to understand how things move and stay still. Together, these rules are called "mechanics." The study of mechanics is...
NASA
Nasa: Kepler and His Laws
This site from NASA provides biographical details about the lives of Tycho Brahe and Johannes Kepler. Discusses Kepler's successes at developing laws of planeatry motion. States the three laws and discusses each one individually....
