... bearing (not the size), as the weight is increased the ball should travel faster since it has more force pushing downwards. * I could also change the size of the ball (not the weight); this would however increase the upthrust and the viscous drag. This means the ball bearing will be travelling towards the bottom of the test tube even slower. This is because more weight is being cancelled out by the greater resistance of the fluid, due to the ball having a larger surface area. * I could increase the size and weight of the ball; this can give me the same readings for speed as smaller ball, which has less weight and surface area only if they are indirect proportion. * I could increase the temperature of the honey this would decrease the viscosity, inversely proportional. Since the viscosity of most fluids are highly dependant on there temperature. In order ...
