What kind of friction exists between solid objects moving in water?static friction
sliding friction
rolling friction
drag

Answers

Answer:

Drag friction.

Explanation:

If you have a solid object, go through air, it experiences drag because the air molecules push back a tiny bit. This drag is enhanced because in water, the molecules are more resistant than air, that's why if you try to run in knee deep water, you experience much more drag than when you are running with your legs out of the water.
