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!

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 ...

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: ...

Fourth-grade students at Jackson Elementary School recently practiced measurement skills and developed an understanding of force and motion by conducting experiments in teams. Brian Hunt, from left, ...

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 ...
