You're sitting in physics class, working on a traditional problem involving forces and acceleration, when you start to wonder where these terms even came from. Were they just dreamed up to bring ...

The science of motion can often surprise you - and an inertia experiment could have the opposite results from what you think!

Explore the difference between calculated forces and constraint forces in this physics-focused video! Learn how to identify, compute, and distinguish between the forces acting on objects, including ...

Find out how forces and motion make our world move in the Science Trek: The Web Show. The world is full of motion and motion happens because of force. On this episode of Science Trek: The Web Show, ...

Some forces are called contact forces because they require objects to touch. One is tension force, found in stretched wires. Another is the force found in a spring. And last are resistive forces: ...

Another theory held that the forces between two particles falls off exponentially in direct relationship to the distance between two particles and that the factor by which it drops is not dependent on ...

Researchers have developed a concise approach to understanding the mechanics of human running. The research has immediate application for running performance, injury prevention, rehab and the ...
