ROTATIONAL MOTION SAMPLE PROBLEMS

Circle Rolling Around A Circle

Rolling Motion without slipping is investigated when a circle rolls around another circle.

WATER PRESSURE in a ROTATING TUBE

Water pressure in a rotating tube on a horizontal plane is investigated. Both rotational motion and fluid mechanics concepts are used.

Rotational Collision of Two Discs

Two discs collide while the one at the bottom was rotating about a fixed axis passing through its center.

Normal Force and Rotating Earth

The rotation of the Earth about its own symmetry axis affects the magnitude and the direction of the normal force acting on the objects.
