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.
Why tips of aeroplanes made pointed?
To reduce friction. making the body streamlined makes the fluid friction less.
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.
Is the velocity of a fluid related to its temperature As in if a fluids velocity while moving through a pipe increases does its temperature increase?
Usually as a fluid moves through a pipe, it will warm up as kinetic energy and pressure is transformed to thermal energy via internal friction within the fluid and friction between the fluid and the walls. It should be noted however that as fluids enter constrictions and then expands out on the other side where pressure is much less, the temperature may actually drop while the fluid velocity increases . This phenomena is commonly observed in the functioning of refrigerators.
Is the limiting friction is always less then rolling friction?
no limiting friction is not less than rolling friction
Why does wax paper have less friction?
less friction then what?
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.
How can you walk on friction less surface when air is present?
Rockets.Or you could walk backward while exhaling and forward while inhaling. This would use air pressure to propel you, and has nothing to do with 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.
If a scientist creates a humanoid robot she will achieve maximum energy efficiency in the robot's joints by increasing the number of?
I will guess: bearings. the more fluid the motion, the less friction. or the joint could be a silicon soft plastic type that flex and allow fluid like motion while maintaining strength.
