Vertical circular motion is a special type of circular motion in which the forces acting on an object change as it moves along a vertical loop. Specifically, the normal force varies throughout the ...

When you swing a ball on a rope in a circle above your head, what keeps it moving in that circular path? This applies to any object moving in a circle, not just a ball on a rope - the force and ...

We solve for centripetal acceleration, centripetal force, and tangential velocity. In this Closer Look segment on circular motion, we investigate circular motion and solve for centripetal acceleration ...

Scientists have classified forces into different kinds. Learn more about friction, applied forces and normal forces and how they work on the Earth and in the universe. Science Trek is available to ...

A high energy electron in circular/spiral motion radiates vortex photons in the entire wavelength range from the radio-wave to the gamma-rays, researchers have shown theoretically and experimentally.
