What is the formula for calculating the moment of inertia of a solid sphere?
The formula for calculating the moment of inertia of a solid sphere is (2/5) m r2, where m is the mass of the sphere and r is the radius of the sphere.
What is the derivation of the moment of inertia of a solid sphere?
The moment of inertia of a solid sphere is derived by integrating the mass of the sphere over its volume, taking into account the distance of each mass element from the axis of rotation. This integration results in the formula for the moment of inertia of a solid sphere, which is (2/5) mass radius2.
What is moment of inertia of solid sphere about its diameter?
The moment of inertia of a solid sphere about its diameter is (2/5)MR^2, where M is the mass of the sphere and R is the radius. This can be derived from the formula for the moment of inertia of a solid sphere about its center, which is (2/5)MR^2, by applying the parallel axis theorem.
Why does the solid disk have a greater moment of inertia than the solid sphere, and how can this difference be explained?
The solid disk has a greater moment of inertia than the solid sphere because the mass of the disk is distributed farther from the axis of rotation, resulting in a larger rotational inertia. This difference can be explained by the parallel axis theorem, which states that the moment of inertia of an object can be calculated by adding the moment of inertia of the object's center of mass and the product of the mass and the square of the distance between the center of mass and the axis of rotation.
What is the formula for calculating the moment of inertia of a hollow sphere?
The formula for calculating the moment of inertia of a hollow sphere is I (2/3) m r2, where I is the moment of inertia, m is the mass of the sphere, and r is the radius of the sphere.
What is the formula for calculating the moment of inertia of a solid sphere?
The formula for calculating the moment of inertia of a solid sphere is (2/5) m r2, where m is the mass of the sphere and r is the radius of the sphere.
How do you derive the moment of inertia of solid sphere?
mass moment of inertia for a solid sphere: I = (2 /5) * mass * radius2 (mass in kg, radius in metres)

What is the moment of inertia of sphere?
Moment of inertia of hollowsphere = 2/5 M(R^5-r^5)/(R^3-r^3)
The moment of inertia of a solid cylinder is?
the moment of inertia of a solid cylinder about an axis passing through its COM and parallel to its length is mr2/2 where r is the radius.
Which will roll down the hill faster a solid cylinder or a solid sphere?
A solid sphere will roll down a hill faster than a solid cylinder due to its lower moment of inertia. The sphere has a greater proportion of its mass closer to its center, allowing it to accelerate more effectively under the influence of gravity. As a result, when both objects are released from rest at the same height, the sphere reaches the bottom first.
How do you determine the moment of inertia?
The moment of inertia of an object depends on its mass distribution and shape. For simple shapes, such as a point mass or a solid cylinder, mathematical formulas can be used to calculate the moment of inertia. For complex shapes, numerical methods or integration techniques may be necessary to determine the moment of inertia.
What is the total energy of a rolling solid sphere?
The total energy of a rolling solid sphere is the sum of its kinetic energy and its rotational energy. The kinetic energy of the sphere is given by 1/2 * m * v^2, where m is the mass of the sphere and v is its linear velocity. The rotational energy is given by 1/2 * I * w^2, where I is the moment of inertia of the sphere and w is its angular velocity.
Can you provide an example problem illustrating the concept of moment of inertia?
Moment of inertia is a measure of an object's resistance to changes in its rotational motion. An example problem illustrating this concept could be calculating the moment of inertia of a solid cylinder rotating around its central axis. The formula for the moment of inertia of a solid cylinder is I (1/2) m r2, where m is the mass of the cylinder and r is the radius. By plugging in the values for mass and radius, you can calculate the moment of inertia of the cylinder.
