Test: Terminal Velocity & Stokes Law - JAMB MCQ

Factors such as temperature, pressure, and density affect the viscosity of a fluid.

As the temperature of a fluid increases, its viscosity generally decreases.

The terminal velocity of an object falling through a fluid is affected by factors such as its mass, the density of the fluid, and the viscosity of the fluid.

When a fluid is described as "thick" in the context of viscosity, it means that the fluid is highly viscous.

According to Stoke's law, the terminal velocity of a spherical object falling through a fluid is directly proportional to its surface area.

The terminal velocity of an object falling through a fluid depends on factors such as the density and viscosity of the fluid but is independent of the object's size.

Among the given options, air offers the least resistance to the motion of an object passing through it.

In Stoke's law, the drag force acting on an object is directly proportional to the object's surface area.

If the viscosity of a fluid decreases while all other factors remain constant, the terminal velocity of an object falling through the fluid will increase.

Higher viscosity leads to lower terminal velocity because a more viscous fluid offers greater resistance to the motion of an object.
