WebThe ball’s speed increases due to the gravitational acceleration (weight) As the speed increases, the fluid resistance increases too (in this case air resistance) Fluid resistance increases until it equals the weight of the ball Terminal speed formula What happens when an ant falls off the empire state building? Subscribe to the Inertia Newsletter WebOct 17, 2024 · Now, applying the formula, η= FL / vA. = F/A ×L/v. =0.0514×10 −3 N sec per Sq m. Thus fluid viscosity is 0.0514×10 −3 N sec per Sq m. Example 2: A submarine experiences a pressure of 5.05 x106 Pa at a given depth of d1 in a sea. When it goes further to a depth of d2, it then experiences a pressure of 8.08 x 106 Pa.
