kinetic theory of gases

by

Kinetic theory of gases The kinetic theory describes a gas as a large number of submicroscopic particles (atoms or molecules), all of which are in constant rapid motion that has randomness arising from their many collisions with each other and with the walls of the container. According to kinetic theory of gases, the molecules of … Read more kinetic theory of gases

Rotational motion, Gravitation, Simple harmonic motion

by

Rotational Motion A rotation is a circular movement of an object around a center (or point) of rotation . A three-dimensional object always rotates around an imaginary line called a rotation axis. If the axis passes through the body’s center of mass, the body is said to rotate upon itself, or spin. A rigid body … Read more Rotational motion, Gravitation, Simple harmonic motion
