Which of the following statement is correct regarding fluid friction?
I. It is also called a drag.
II. It depends on the speed of the object with respect to the fluid.
Show answer & explanation
Correct answer: C
Explanation
Correct Answer:
Both 1 and 2
Explanation:
Fluid Friction is also known as drag, so statement 1 is correct.
Statement 2 is also correct because fluid friction depends on the shape of the object and its speed—higher speed leads to greater friction.
Key Points:
• Fluid friction = Drag
• Depends on: Shape and speed
Additional Facts:
• Fluids include both liquids and gases.
• Air Resistance is a common example of fluid friction.
