A solid typically has very little particle motion compared to liquids and gases. The particles in a solid are closely packed and vibrate in fixed positions, which restricts their ability to move around freely. This leads to solids having a definite shape and volume.
In particle theory, motion is often explained as the movement of particles through space. The particles can exhibit various types of motion, such as linear, circular, or random motion, depending on the forces acting upon them. Overall, particle theory helps us understand how objects move and interact at a very small scale.
The energy possessed by a particle due to its motion is called kinetic energy. It depends on the mass of the particle and its velocity.
The measure of energy of motion of a particle of matter is called kinetic energy. It is calculated using the formula KE = 0.5 * mass * velocity^2, where mass is the mass of the particle and velocity is its speed.
Shear waves travel perpendicular to the direction of particle motion, which results in the particle motion being parallel to the wave's direction. The energy of a shear wave is mainly associated with the shearing or twisting motion of particles in the medium, as opposed to the compression and expansion seen in longitudinal waves.
When energy decreases, the particle motion usually slows down. This can manifest as a decrease in kinetic energy and a reduction in the speed at which particles move.

Particle motion increases as energy (like heat) is added. The motion slows as energy leaves. Temperature is a measure of this change in particle motion.

Particle motion and thermal heat energy should both be increasing

The particle motion in shear waves relative to the energy of the wave is downward.
A stationary particle.
There are three general types of mechanical waves: – Transverse – particle motion is perpendicular to wave motion. – Longitudinal – particle motion is in the same direction as wave motion. – Combined – sea waves.
The key difference between a particle and a rigid body is that a particle can undergo only translational motion whereas a rigid body can undergo both translational and rotational motion
