Linear VelocityDefinition Formula Units Examples

Linear velocity is the measure of "the rate of change of displacement with respect to time when the object moves along a straight path.". It is a vector quantity. Dimension formula of linear velocity is M 0 L 1 T -1. Linear and angular velocities are related to the speed of an object based on the perspective chosen.

Identifying airborne transmission as the dominant route

 · We have elucidated the transmission pathways of coronavirus disease 2019 (COVID-19) by analyzing the trend and mitigation measures in the three epicenters. Our results show that the airborne transmission route is highly virulent and dominant for the spread of COVID-19. The mitigation measures are discernable from the trends of the pandemic. Our analysis reveals that the difference with and
