Boats usually have low friction (drag) compared to freight trains, but they have considerably more drag than most aircraft, especially the really fast ones. The faster the boat or aircraft, the lower the friction.
Yes, a boat moving on the water has some friction with the water and some with the air through which it moves, although very little.
High to Low.
No lubricating oils are not. The reason is that they have to be able to withstand heat from friction of moving engine parts etc. They have very high boiling points and thus very low volatility.
2 high tides and 2 low tides in one day. All of them have different heights (Ex. One high high tide, then one high low tide, then a low high tide, then a low low tide.
high pitch is high frequency, low pitch is low frequency
what is the movment of monomers from high to low
it is low friction i think
Friction is high on a carpet.
low
Hockey. Low friction when the player is gliding down the ice. High friction when he is propelling himself down the ice.
low
low friction
Friction can be very useful in your life. You need low friction when you ski. If you have high friction you cannot glide easily on the snow. You can also use low friction when you ice skate. If you have high friction you cant glide across the ice. When you use your laptop your keypad has to be able to glide. Some examples of high friction are erasing with your pencil, rubbing your hands together etc.
high
it gets hot
Low friction is slippery high friction has good traction. In the sport of Curling (gliding those heavy granite stones on ice towards a bullseye) one shoe has low friction (to slide on the ice) the other has high friction (to propel the player).
first they are called cleats not boots and they dont have friction.
High friction and low friction.
