## What does rotation 180 degrees about the origin mean?

Rotation of a point through 180°, about the origin when a point M (h, k) is rotated about the origin O through 180° in anticlockwise or clockwise direction, it takes the new position M’ (-h, -k). …

## Which of the following is a real life example of rotation?

Real life examples of rotations are: strumming a guitar. hitting a nail with a hammer. walking.

## What is the effect of rotation of Earth on our lives?

It gives day and night, an integral part within the evolution of life (and its behaviour) on the planet. The temperature shift helps drive weather, as does the spin of the earth itself. And seasons come and go as the spin tilts. The atmosphere is protected by magnetic fields created by the spin.

## What does the rotation of the earth cause us to experience?

Earth rotates on its axis; this causes us to experience day and night. Because of this tilt and Earth’s movement around our Sun, there is a time when Earth’s north pole is tilting 23.5 degrees toward our Sun.

## What does rotation of the earth cause?

Each planet rotates, or spins, on its axis. The rotation of the Earth on its axis causes day and night. As the Earth rotates, only one-half of the Earth faces the sun at any given time. Because of this direction of rotation, we see the sun rising every day in the east and setting in the west.

## What is the effect of rotation of the earth on the acceleration due to gravity?

Answer: Acceleration due to gravity is minimum at the equator and maximum at the poles. At poles; φ = 90° g’ = g So, acceleration due to gravity is maximum at poles. Hence, acceleration due to gravity decreases due to rotation while it increases due to increase in latitude.

## Does rotation of Earth affect gravity?

While the spinning of the Earth doesn’t directly affect gravity, it does off-set it a little. At the north and south poles objects weigh exactly what they should, and at the equator things weigh slightly less. The farther you are from the Earth’s axis the more centrifugal force you’ll experience.

## What is the effect of shape of Earth on value of G?

Answer. This value of g will increase as one goes very high from the surface of the earth because the distance between the object and the earths center would increase drastically.

## What is acceleration due to gravity where the value of g is maximum and minimum on the surface of Earth and why?

Find the difference in the maximum and minimum value of g on the surface of the earth. Thus, acceleration due to gravity is maximum at poles. Thus, acceleration due to gravity is minimum at the equator. Two heavy spheres each of mass 100 kg and radius 0.10 m are placed 1.0 m apart on a horizontal table.

## At what position on Earth is the acceleration due to gravity maximum and minimum?

The value of acceleration due to gravity is maximum at poles and minimum at equator.

## Why is gravity 0 at the center of the Earth?

If you are at the center of the earth, gravity is zero because all the mass around you is pulling “up” (every direction there is up!). The farther you are from the spin axis, the lower “gravity” is, because another force (centrifugal, or centripetal) caused by the spin pulls you in the opposite direction.

## Why does the earth impart the same acceleration to all bodies?

Yes earth imparts same acceleration to all bodies because anything is neglible as compared to the size of earth. The acceleration is due to the application of gravitational force of earth.
