Viscosity is the resistance of a fluid to flow.
Viscosity is the resistance of a fluid to flow.
The unit for viscosity coefficient can be measured in MKS (SI) or CGS units.
The unit for viscosity coefficient can be measured in MKS (SI) or CGS units.
The viscous force opposing the motion of the steel ball depends directly on the speed of the ball.
The viscous force opposing the motion of the steel ball depends directly on the speed of the ball.
The terminal velocity is the constant speed at which the ball moves when the viscous force and buoyant force balance the weight of the ball.
The terminal velocity is the constant speed at which the ball moves when the viscous force and buoyant force balance the weight of the ball.
The steel ball decelerates and eventually comes to a stop before reaching the bottom of the jar.
