What is the moment of inertia of Earth about its diameter?
Therefore, moment of inertia of the earth about its diameter is 1.638×10^38 kgm².
What is the moment of inertia of the earth about the sun?
0.3307
Solar System values
| Body | Value | Notes |
|---|---|---|
| Sun | 0.070 | Not measured |
| Mercury | 0.346 ± 0.014 | |
| Venus | 0.337 ± 0.024 | |
| Earth | 0.3307 |
What are the moments of the earth?
Rotation and Revolution are two motions of the earth. When earth spins or rotates around its axis, that movement of spinning is called Rotation of Earth. And when earth spins or revolves around the sun, that movement is called Revolution of Earth.
How do you find the moment of inertia of a planet?
Moments of inertia can also be calculated from the quadrapole moment of the gravity field of a planet, but such data are only available for Earth, Moon, Mars and Venus. This simplifies to L=2/5 for a uniform sphere (for rχ=0 or rχ=R).
What is the moment of inertia of a I ring II Disc III soild sphere about its diameter?
I=25MR2, where M is the mass and R is radius of the solid sphere.
What is the rotational kinetic energy of Earth in its orbit around the sun?
The rotational kinetic energy of Earth in its orbit around the Sun is 2.67 × 1033 J.
Does the earth spin because of inertia?
The reason is something called ‘inertia. ‘ The Earth always spins toward the east. That’s inertia. Because of inertia, everything on Earth moves right along with it as our world spins on its axis, as it moves in orbit around the sun, and as the sun moves around the center of the galaxy.
What is the moment of inertia of a solid sphere?
EXPLANATION: The moment of inertia of a solid sphere of mass ‘M’ and radius ‘R’ about its diameter is….Detailed Solution.
| Body | Axis of Rotation | Moment of inertia |
|---|---|---|
| A solid cylinder of radius R | axis of the cylinder | M R 2 2 |
| A hollow sphere of radius R | diameter | 2 3 M R 2 |
| A hollow cylinder of radius R | Axis of cylinder | MR2 |
Can you see Earth rotate from space?
Originally Answered: Why can’t we see earth spinning from space? The simple answer is that the earth is very large. So large that even though its surface is traveling 1,600 km/h at the equator, it still takes en entire day to complete one rotation.
What is Neptune’s moment of inertia?
C – moment of inertia….moment of inertia factor.
| sphere of uniform density | 0.4 |
|---|---|
| Uranus | 0.23 |
| Neptune | 0.23 |
