This study is briefings the roles of volume fraction, Coriolis, and Lorentz forces on the dynamics of rotating water based silver tiny particles flow toward a continuously stretching sheet. The Coriolis force play a significance role on the dynamic of fluid in oceanography, Astrophysics, meteorology, and Stellar dynamics by effecting the fluid movement on the earth surface. The nanoparticles are incorporated because of their unusual qualities like upgrade the thermal transportation, which are very important in heat exchangers, modern nanotechnology, electronics, and material sciences. The primary goal of this study is to improve heat transportation. Appropriate similarity transformations are applied for the principal PDEs to transform into nonlinear dimensionless PDEs. A widely recognized Numerical scheme known as the Finite Element Method is employed to solve the resultant convective boundary layer balances. It is seen that growing contributions of the Coriolis, and Lorentz forces cause to decline the primary and secondary velocities, but the temperature function and skin friction factor show opposite trend. The temperature distribution and reduced Nusselt number are prominent against growing volume fraction, but inverse trend is observed for velocities distributions. These examinations are relevant to the field of plastic films, crystal growing, paper production, heat exchanger, and bio-medicine.
