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, ...

Gravity is the force of action between two objects. It’s called a natural force because it acts at a distance rather than needing to be in contact. Gravity is the force that holds us down on Earth and ...

We are at a critical time and supporting climate journalism is more important than ever. Science News and our parent organization, the Society for Science, need your help to strengthen environmental ...

All of the objects in our solar system are acted upon by forces. Forces are pushes or pulls. Every force has both a strength and a direction. Applying a force on something–like pushing a toy car–can ...

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 ...

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 ...

“I am one with the Force, the Force is with me.” In an hour, we will take on some of the science behind the movies – experimenting with forces and motion, using angles of incidence and refraction to ...

Learn the key differences between centripetal and centrifugal forces, their real-world applications in physics, and how they shape our understanding of circular motion. When you purchase through links ...

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 ...

When a musician strums a guitar, the vibration of the strings creates sound waves that human ears hear as music. When a guitar string is plucked, it moves a certain distance, depending on how hard the ...
