Question

Which type of friction occurs when an object moves through a liquid or gas? *

Answer 1

Static, sliding, and rolling friction occur between solid surfaces. Static friction is strongest, followed by sliding friction, and then rolling friction, which is weakest. Fluid friction occurs in fluids, which are liquids or gases

Answer 2

Fluid friction occurs when an object moves through a liquid or gas.

• Fluid friction is friction that occurs when things move through a fluid. A fluid is a liquid that can flow and conform to the shape of its container. Liquids and gases are examples of fluids.
• Fluid friction is something you've probably encountered if you've ever tried to push your open palm through the water in a tub or pool. You can feel the water's resistance against your hand.
• Take a look at the skydiver. He's using a parachute to plummet back to Earth. The air resistance against the parachute slows his descent.
• The more fluid friction resisting the motion of a moving item, the quicker or bigger it moves. As a result, the parachute experiences more air resistance than the skydiver's body.
