- Understanding Earths Spinning Speed: A Simple Explanation - Physics Forums
The cosine of 45 is 0 707, so the spin speed at 45 degrees is roughly 0 707 x 1037 = 733 mph (1,180 km h) That speed decreases more as you go farther north or south By the time you get to the North or South poles, your spin is very slow indeed — it takes an entire day to spin in place "Can anyone explain all of this please? In layman's terms!
- Counteracting the inertia of Earths rotation - Physics Forums
What you have been conceptualising as countering here - the spin of the Earth - is velocity In common parlance the distinction can be blurry When viewed from a non-rotating reference frame - here it means the point of view of the Sun and the background stars - a point at the surface of the Earth at the equator has some linear velocity
- Why Doesnt Earths Rotation Affect Flight Times? - Physics Forums
Alright then, the Earth is traveling at 1040 mph we human or other objects are attached to the Earth by the gravitational force so it means that we are also traveling at 1040 mph speed toward west 1) So, if we go toward east at a speed of 1040 mph what will happen?
- Why doesnt the Earth at the equator experience a sonic boom?
The Earth's circumference at the equator is 24,901 miles, or 40 075 million meters It rotates completely once a day or in 86400 seconds The speed of sound is 343 m s and the Earth moves at the equator at 40 075 million m 86400 s = 463 831019 m s which is clearly faster than the speed of
- Is the Spin of Earth Constant Throughout the Year? - Physics Forums
No The Earth's rotation rate is not constant The rotation rate undergoes secular, periodic, and seemingly random changes The secular changes result from the Earth transferring angular momentum to the Moon This is a very real, measurable effect The length of one day (midnight to midnight) is increasing by about 2 3 milliseconds per century
- Does the rotation speed of a planet affect its gravitational pull
The full force of gravity is offset to a small amount by the centrifugal force Or, more precisely, some of the gravity is used as a centripetal force to keep us rotating with the Earth This, however, does not affect objects in orbit The moon's orbit is essentially unaffected by the Earth's spin
- Im wondering about air travel and the rotation of the earth
I get that when the plane LEAVES the Earth it moves at its speed PLUS the rotation of the earth, but surely the effect of the Earth's momentum from its spin on the plane would decrease and go away very quickly and predictably
- Why does the atmosphere move with the earth? - Physics Forums
NateTG points out: the rotation of the Earth during the movement of air north and south along the Earth has significant and important effects on weather which indicates to me that the constant thrust of the Earth is needed to maintain the speed of the atmosphere the farther it is from the centre
- Earths Velocity without the Moon: Formula Answers - Physics Forums
the net force of the Earth onto the moon is zero the moon moves in a circular motion, if you take the infinately many directions of the the force of the moon, it should add to zero our Earth actually moves around the sun in a sine cos motion due to the moons gravitational force but on average the speed of Earth is unchanged simplest explination
- What Could Cause the Earths Rotation to Dramatically Slow Down?
Now if the Moon is also there, tidally locked to the Earth at 47 days, most of the angular momentum internal to the Earth-Moon system is in the Moon's orbit, not the Earth's spin, so as the Sun tries to spin down the Earth, the Moon's angular momentum keeps getting dumped back into the Earth, as you say
