Our simulation reveals that the dynamics of a self-propelled spherical particle significantly depends on two independent dimensionless parameters of the particle: the ratio of the self-propulsion velocity to the characteristic thermal velocity and the ratio of the friction coefficient to the rotational diffusion coefficient. The time-dependent mean square displacement and mean linear displacement (the noise-averaged trajectory) of the particle are investigated as a function of medium viscosity, self-propulsion velocity and moment of inertia. The calculations are performed using a mathematical model of a self-propelled Brownian sphere with translational and rotational inertia. This paper presents the numerical simulation results of active Brownian motion in homogeneous media of different viscosities. At present, there is a lack of statistical theory describing the underdamped Brownian motion of self-propelled particles at all time scales. A distinctive feature of such a medium is an extremely low viscosity at which the inertial effects play a significant role, resulting in underdamped Brownian motion. Recently, experiments with Janus particles in a low-pressure plasma have appeared. In most studies the self-propelled Brownian particles move in overdamped media. Such particles autonomously convert the available energy of the environment into their own directed mechanical motion. The Brownian motion also causes the particles to spread out over time.Self-propelled colloids, active polymers and membranes, driven (vibrated) granular layers and hybrid synthetic-biological systems are striking examples of systems containing synthetic active Brownian particles. This collision causes the particles to move in a random direction. The Brownian motion of the particles causes them to collide with the molecules in the liquid or gas. The motion of the particles can seen by suspending a small particle in a liquid or gas and observing it with a microscope. The magnitude of the Brownian motion is proportional to the temperature of the liquid or gas and the size of the particles. This motion called Brownian motion after the botanist Robert Brown who first observed it in 1827. The motion of particles in a liquid or gas is due to the random thermal motion of the molecules. The collisions cause the particles to move around randomly. The cause of Brownian motion is the collisions between the particles in a fluid and the surrounding molecules. The Brownian motion continues until the thermal energy of the particles is equal to the thermal energy of the surrounding fluid. The thermal energy causes the molecules to move around randomly, and this movement transferred to the suspended particles. The Brownian motion caused by the thermal energy of the molecules in the surrounding fluid. The movement of the particles can be seen with a microscope, and it is particularly obvious when the particles are illuminated with a light beam. The particles usually less than 1 micrometer in size, and they suspended in a liquid or gas. The Brownian motion most easily observed in a suspension of small particles in a fluid. The Brownian motion named after the botanist Robert Brown, who first observed the phenomenon in 1828. The particles constantly buffeted by the surrounding fluid molecules, and this movement results in a chaotic jittering motion. The Brownian motion describes the random movement of particles suspended in a fluid. The tiny particles constantly buffeted by the molecules around them, and this motion causes them to move around chaotically. The Brownian Movement is the movement of tiny particles (such as atoms or molecules) in a liquid or gas, caused by the random motion of the molecules in the liquid or gas. What is the Brownian Movement in Chemistry? This movement is caused by the thermal energy of the particles. The particles are constantly moving around and bouncing off of each other. The Brownian Movement is the random movement of particles in a fluid.
