if in a motion the axis of the rotation passes through an object then the motion is called
Rotation A rotation is a circular movement of an object around a center (or point) of rotation. A three-dimensional object can always be rotated around an infinite number of imaginary lines called rotation axes (/ˈæksiːz/ AK-seez). If the axis passes through the body's center of mass, the body is said to rotate upon itself, or spin. A rotation about an external point, e.g. the Earth about the Sun, is called a revolution or orbital revolution, typically when it is produced by gravity. The axis is called a pole.
Somersault A somersault (also flip, heli, and in gymnastics salto) is an acrobatic exercise in which a person's body rotates 360° around a horizontal axis with the feet passing over the head.[1] A somersault can be performed forwards, backwards, or sideways and can be executed in the air or on the ground. When performed on the ground it is typically called a roll. Somersault originates from an obsolete French word, sombresault, from Occitan sobresaut; and ultimately Latin – supra, "over", and saltus, "jump".
