Tugging a small toy with your dog can be a lot of fun—but it’s also a great way to experiment with forces acting on an object. Forces are what scientists call the pushing and pulling on objects. In ...

Why is pancake syrup an example of a resistive force? Some forces are called contact forces because they require objects to touch. One is tension force, found in stretched wires. Another is the force ...

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, ...

Physics, particularly forces and motion, can be challenging. By observing everyday motion, conducting simple experiments, and understanding Newton's laws in plain language, the concepts become more ...

I saw it again. This time it was an introduction to an interesting online look at introductory physics. I was excited---but then, I wasn't so excited. Right there in the first video they talked about ...

Rolling-ring drives are friction drives that convert the constant rotary motion of a plain shaft into a traversing action that moves an attached carriage. Used in positioning and reciprocating ...

Physics, especially the part about forces and motion, often feels like a maze of confusing concepts and formulas. If you’ve ever stared at a problem about an object moving or a force acting and ...
