Is angular acceleration proportional or inversely proportional to torque?
Proportional.For linear movement, Newton's Second Law states that force = mass x acceleration.The equivalent for rotational movement is: torque = (moment of inertia) x (angular acceleration).Proportional.For linear movement, Newton's Second Law states that force = mass x acceleration.The equivalent for rotational movement is: torque = (moment of inertia) x (angular acceleration).Proportional.For linear movement, Newton's Second Law states that force = mass x acceleration.The equivalent for rotational movement is: torque = (moment of inertia) x (angular acceleration).Proportional.For linear movement, Newton's Second Law states that force = mass x acceleration.The equivalent for rotational movement is: torque = (moment of inertia) x (angular acceleration).
What increase the moment of inertia?
A rotating body that spins about an external or internal axis (either fixed or unfixed) increase the moment of inertia.
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.
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)

How angular momentum is equals to kgms?
Angular momentum is calculated as the product of a rotating object's moment of inertia (I) and its angular velocity (ω). The units of angular momentum are kg m^2/s, which is the same as the units for moment of inertia multiplied by angular velocity (kg m^2 * 1/s). This relationship is based on the principles of rotational motion and conservation of angular momentum.
What moment of inertia does not depend on angular velocity?
The moment of inertia of an object does not depend on its angular velocity. Moment of inertia is a measure of an object's resistance to changes in its rotational motion, based on its mass distribution around the axis of rotation. Angular velocity, on the other hand, describes how fast an object is rotating and is not a factor in determining the moment of inertia.
What quanties are needed to calculate angular momentum?
To calculate angular momentum, you need the object's moment of inertia, its angular velocity, and the axis of rotation. The formula for angular momentum is given by L = I * ω, where L is the angular momentum, I is the moment of inertia, and ω is the angular velocity.
Does the moment of inertia give an object's resistance to changes in angular velocity?
Yes, the moment of inertia quantifies an object's resistance to changes in its rotational motion or angular velocity. Objects with a higher moment of inertia require more torque to accelerate or decelerate their rotation compared to objects with a lower moment of inertia.
Why is angular momentum of a body is equal to the product of its moment of inertia and angular velocity?
The angular momentum of a rotating body is equal to the product of its moment of inertia (a measure of its resistance to angular acceleration) and its angular velocity (rate of rotation) because angular momentum is a measure of how much rotational motion a body possesses, and both moment of inertia and angular velocity contribute to this rotational motion. Just like how linear momentum is the product of mass and velocity in linear motion, the product of moment of inertia and angular velocity gives the rotational equivalent of momentum.
What is ment by angular momentum and angular velocity?
Angular momentum is a measure of an object's rotational motion, calculated as the product of its moment of inertia and angular velocity. Angular velocity, on the other hand, is the rate of change of angular displacement of an object rotating around an axis. It is measured in radians per unit time.
How does the skater decrease his moment of inertia and increase his angular velocity?
The skater can decrease his moment of inertia by bringing his limbs closer to his body, which decreases the distribution of mass. To increase his angular velocity, the skater can generate more angular momentum by pushing off the ice with greater force, allowing for a faster spin.
What structure is involved in angular acceleration?
Angular acceleration is a measure of how quickly the angular velocity of an object is changing. It involves the object's moment of inertia and the net torque acting on it. When a torque is applied to an object with a certain moment of inertia, it causes the object to accelerate rotationally.
What quantities are needed to calculate angular momentum?
To calculate angular momentum, you need the object's moment of inertia (a measure of its mass distribution), its rotational velocity, and the object's shape. The formula for angular momentum is L = Iω, where L is the angular momentum, I is the moment of inertia, and ω is the angular velocity.
Why moment of inertia is also called rotational inertia?
Because it is a measure of the "resistence" of an object to be accelerated in its rotation. An object with a big moment of inertia is more difficult to increase/decrease its angular velocity (speed of rotation), than an object with a low moment of inertia.
When a spinning skater pulls in her arms to turn fasterher angular momentum?
When a spinning skater pulls in her arms to turn faster, her angular momentum is conserved. Angular momentum is the product of an object's moment of inertia and its angular velocity. By pulling her arms in, the skater decreases her moment of inertia, causing her angular velocity to increase in order to maintain a constant angular momentum. This is similar to the principle of conservation of angular momentum seen in other rotating systems.
What is the relation between torque and angular acceleration?
Torque is the rotational equivalent of force and is responsible for causing rotational motion. Angular acceleration is the rate at which an object's angular velocity changes. The relationship between torque and angular acceleration is defined by Newton's second law for rotation: torque is equal to the moment of inertia of an object multiplied by its angular acceleration.
