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

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

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

The equation of centripetal acceleration is derived in this problem. #rotationalmotion #calculus #physicspractice
