Is swimming a fricton?
Yes. In physics, the types of friction include: static friction, sliding friction, rolling friction, and fluid friction. Water has fluid friction. This is considerably less than static friction, but it's there. Fluid friction also includes other liquids and air (things that flow).
When is friction in swimming good?
If you're in competitive swimming, friction will only slow you down, so the answer is no.However, without it, you'll simply fall like a rock to the bottom of the pool or ocean or wherever you're swimming. So if you're just swimming for survival, then it will be desirable.AnswerWhen an object is moving through a fluid, the term is "drag" not friction, and no drag is not desirable which is why swimmers remove all the hair on their bodies. Buoyancy keeps you from sinking not friction; friction is a reaction force.
What one needs less force to move sliding friction or fluid friction?
Fluid friction.
What Lubricants reduce friction by replacing sliding friction with fluid friction?
Viscous lubricants, such as oils and greases, reduce friction by creating a fluid layer between moving surfaces. This fluid layer separates the surfaces, allowing them to slide past each other with less resistance. The viscosity of the lubricant determines the effectiveness of this fluid friction.
Why tips of aeroplanes made pointed?
To reduce friction. making the body streamlined makes the fluid friction less.
Do the fluid friction is minimum for objects that have a streamlined shape?
Yes, objects with a streamlined shape experience less fluid friction compared to objects with a less aerodynamic shape. The streamlined shape helps in reducing drag by allowing the fluid to flow smoothly around the object, thereby minimizing resistance.
What is the relationship of internal friction and viscosity?
yes
How is physics applied to swimming?
1st Law: You must paddle to move. If the force of your stroke exceeds fluid friction you will accelerate. If the force of your stroke is less than fluid friction you will slow down. If the force of your stroke equals the fluid friction you will swim at constant speed. You must exert force on the wall of the pool (flip turn) to change direction. 2nd Law: The acceleration of your stroke is defined by F = MA where F is the net force of your stroke and M is your mass 3rd Law: The force of your stroke on the water is equal to the force of the water on your stroke.
Why does wax paper have less friction?
less friction then what?
Is the limiting friction is always less then rolling friction?
no limiting friction is not less than rolling friction
Do you have to take earings out while swimming?
When swimming in a luxury pool, it is not as mandatory, however it is recommended in a more competitive pool. Less resistance the better.
Does rolling friction have more friction than fluid friction?
Here's the trick. Rolling friction is static friction. Sliding, or kinetic, friction is another thing, but when an object rolls without slipping, the point touching the ground at any instant is not moving at all, and so is subject to static friction.
