Velocity Speed in a particular direction is called Velocity. The units for velocity can be implied from the definition to be meters/second or in general…

Vibratory motion is a type of motion in which a particle moves to and fro about a fixed point. It occurs at a fixed point as…

Periodic motion is a physics term meaning the repetition of the same motion in the same amount of time. Observe the motion of the hand…

Translational Motion Translational motion is the movement of an object from one point to another through space. An example of this is a bullet fired…

A triatomic Molecule non-linear molecule may rotate, about the three mutually perpendicular axes, as shown in Figure. Therefore, it possesses three degrees of freedom of rotation…

In the case of the triatomic molecule of linear type, the centre of mass lies at the central atom. It, therefore, behaves like a diamotic…

The diatomic molecule can rotate about an axis at right angles to its own axis. Hence it has two degrees of freedom of rotational motion…

Refraction has many applications in optics and technology. A lens uses refraction to form an image of an object for many different purposes, such as…

Refraction of sound or waves involves a change towards sound or waves as they pass in one medium to an additional. Refraction of the path…
