Does mass affect terminal velocity?
YES. Ignoring wind resistance and/or air friction, all objects fall at the same rate of acceleration, 9.81m/s^2. If hypothetically no air resistance/friction is present, then all objects would reach the same terminal velocity regardless of mass. In practice though, wind resistance can be significant – objects like feathers and leaves – and the terminal velocity is only reached when the the air resistance force is equal to the gravitational force. A rubber ball of diameter 2cm will fall at the same rate as a lead ball of 2cm diameter, but the lead ball will have greater momentum upon impact. So yes mass does affect TV, but it is important not to confuse the fact that all objects are subject to the same downward acceleration.
