Net Force Of Zero Velocity. The initial speed is zero so drag force is zero. Newtons nd2 law.
This equation says that a net force of zero implies that the velocity v of the object is constant. Force is not required for an object to continue moving or staying at a state of rest. The initial speed is zero so drag force is zero.
The net force on the drop is zero because the weight of the drop is balanced by the upthrust and the viscosity of air.
This equation says that a net force of zero implies that the velocity v of the object is constant. This equation says that a net force of zero implies that the velocity v of the object is constant. If there is a large pressure build up on the rebound side due to the stack and. The initial speed is zero so drag force is zero.
