i believe it is linear
They are slowing it.
Yes.
Yes. The energy from the tides ultimately comes from Earth's rotation; due to friction during the tides, Earth's rotation will logically get slower and slower.
Earth's rotation is slowing slightly with time; thus, a day was shorter in the past. This is due to the tidal effects the Moon has on Earth's rotation.
The Earth's rotation rate would remain fairly constant if there was no moon to affect it. The moon plays a role in slowing down Earth's rotation over very long periods of time due to tidal forces. Without the moon, the Earth's rotation would not experience significant changes in speed.
It would depend on the degree and time frame of change and how that change was brought about. The rotation of the earth is very slowly changing. It is slowing down.
It slow down the rotation of the earth due to friction of water motion acting on to earth surface. The earth spin is slowing down by about 1.5-2 milliseconds per century.
Yes, tidal friction is causing Earth's rotation to gradually slow down over thousands of years. This is due to the gravitational forces between Earth and the Moon, which create tidal bulges on Earth's surface that slightly offset its rotational momentum.
The earth's rotation is gradually slowing down - it has been for eons - but the rate is on the order of 1-2 seconds per century.
The linear speed of the Earth's rotation at any latitude can be calculated by multiplying the cosine of the latitude by the equatorial rotational speed of the Earth, which is approximately 1670 kilometers per hour (1037 miles per hour). At latitude 60.24 degrees north, the linear speed of the Earth's rotation would be approximately 835 kilometers per hour (519 miles per hour).
Yes, the Earth slows down a little more each year. Reason being that the Moon is moving further away from us, and friction from the tides also causes the rotation of the earth to slow. The rate of slowing is very small in a human lifetime, but is significant over millions of years. It is estimated that the Earth, a million years from now, will take about 15 seconds longer to rotate. (You may have heard that "leaps seconds" are added to the year every few years. That is a complicated subject and the slowing of the Earth's rotation is only part of the explanation.)
No. Just the opposite. The earth's rotation is slowing down because of the gravitational force between the earth and the moon. The day is getting longer by something like a millisecond (0.001 second) every hundred years.
