The sensation of your surroundings still rotating after you've stopped spinning is due to the inertia of the fluid in your inner ear, which helps regulate balance. When you spin, the fluid moves in response to the motion, and when you stop, it continues to move for a brief period, sending signals to your brain that you are still in motion. This discrepancy between visual input and inner ear signals creates the illusion of ongoing rotation. It can also be enhanced by the way your brain processes motion and spatial awareness.
Yes. For the object not to move, two conditions must be satisfied: (1) The vector sum of forces must be zero, and (2) The vector sum of torques must be zero. Do some reading on torque, for more information.
Because it's in line with the Earth's north and south poles, so as we sit watching from our rotating Earth its direction does not alter. Imagine sitting on a swing as it goes round. If you look at the centre, its direction stays fixed, as the rest of your surroundings appear to rotate.
Those are called sunspots. They are regions that are ca. 1200 kelvin colder than the surroundings. The resulting temperature is still very hot compared to our everyday experience, but that's what makes the spots darker than the surroundings.
Yes. The ecliptic plane is the plane of the earth's orbit around the sun. From where we sit, it appears as the path (line) that the sun travels through the stars. The 'signs' of astrology originated as the constellations along that line. All of this is associated with the earth's revolution around the sun, not its daily rotation.
If there is no net force acting on an object then the movement of the object doesn't change. If it is sitting still, then it remains sitting still. If it is moving, then it continues moving at the same speed in the same direction.
No
It rotates and revolves around the Sun like any other planet
it would still appear to rotate
it would still appear to rotate
No
square. rotate a square and it's still looks the same rotate a trap and you can tell it's on its side
An artificial satellite's power is for its radio, not to maintain its orbit. Vanguard, the Navy satellite, ran out of power decades ago, but it had such a good orbit, it's still out there. Someday somebody will find it again, whirling around the Earth in silence.
so it can hide underwater and still see his surroundings
No, it is not compulsory for every Muslim. Actually, Whirling Dervish is a sufi kind of dance, practiced in Turkey and its purpose is to feel unity with Allah. This tradition was started in reference with Jalal-ud-Din Rumi, who was one of the major Muslims mystics and is still revered in all over the World, including Turkey.
If the Earth didn't rotate, the Moon would still rise in the east and set in the west due to its own orbit around the Earth. The apparent movement of the Moon in the sky is primarily due to the Earth's rotation; however, the Moon's motion would still follow its own path regardless of Earth's rotation.
