How Temperature Affects the Intensity of Brownian Motion

As temperature increases, the kinetic energy of fluid molecules rises, resulting in more vigorous and intense Brownian motion.

Difference Between Brownian Motion and Other Types of Particle Motion

Brownian motion is characterized by its random, erratic paths due to collisions with fluid molecules, unlike predictable motion types such as ballistic or uniform circular motion.

Practical Applications of Brownian Motion in Science and Engineering

Brownian motion is used in nanotechnology, colloidal science, diffusion processes, and statistical mechanics, aiding in material development and stability analysis.

Causes of the Random Motion of Particles in Brownian Motion

The random motion in Brownian motion is caused by thermal agitation from surrounding fluid molecules colliding with suspended particles.
