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 ...

This change in velocity directly matches up with the net downward force from gravity and the normal force from the surface. What this tells us is that circular motion requires a net force pushing ...

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 ...

Segment 3G: Circular Motion We explore the concept of circular motion. Segment 3G: Circular Motion We travel to an amusement park to explore circular motion. We work through an example problem and ...
