# Conservation of angular momentum

The law of conservation of angular momentum states that the angular momentum of a system will remain constant unless an external torque is applied. This means that if a robot is spinning, it will continue to spin unless something stops it. The angular momentum of a system can be calculated by taking the product of the mass, velocity, and radius of the object.

##### What is law of conservation of angular momentum give example?

The law of conservation of angular momentum states that the angular momentum of a system remains constant unless an external torque is applied. This law is also known as the law of inertia of angular momentum.

One example of the law of conservation of angular momentum is a spinning top. If the top is spinning quickly and there is no external torque applied to it, the angular momentum of the top will remain constant. However, if an external force is applied to the top (such as when someone bumps into it), the angular momentum of the top will change.

#### What is law of conservation of angular momentum Class 11?

The law of conservation of angular momentum is one of the most important laws in physics. It states that the angular momentum of a system is constant if there are no external forces acting on the system. This law is a direct consequence of Newton's second law of motion, which states that the total force on a system is equal to the rate of change of momentum of the system.

The angular momentum of a system is the sum of the angular momenta of all the objects in the system. The angular momentum of an object is the product of its mass, its velocity, and its distance from the axis of rotation.

The law of conservation of angular momentum can be used to explain many phenomena in the world around us. For example, it can be used to explain why a spinning top does not fall over. The top has a large angular momentum because of its high speed of rotation. This angular momentum is constantly being lost due to friction with the air. However, the top is able to maintain its angular momentum because it has a small mass. As the top loses angular momentum, it also loses energy. The top eventually stops spinning because it has lost all of its energy.

The law of conservation of angular momentum can also be used to explain why a planet orbiting the sun does not fall into the sun. The planet has a large angular momentum because of its high speed of orbit. This angular momentum is constantly being lost due to the gravitational force of the sun. However,

##### What is conservation of angular momentum and conservation of energy?

The law of conservation of angular momentum states that the angular momentum of a closed system remains constant. The law of conservation of energy states that the total energy of a closed system remains constant.

In a robotic system, these laws help to ensure that the system remains stable and efficient. By conserving angular momentum, the system can avoid changes in its rotational speed that would otherwise require additional energy to maintain. Similarly, by conserving energy, the system can avoid wasting energy on unnecessary tasks.

#### What is angular momentum example?

Angular momentum is the product of the moment of inertia of a rotating object and its angular velocity. It is a measure of an object's rotational motion.

The angular momentum of a spinning top, for example, is the product of the top's mass, its radius, and its angular velocity. The larger the mass, radius, or angular velocity, the greater the angular momentum. What is the unit of angular momentum? The unit of angular momentum is the kilogram meter squared per second (kg-m^2/s). This unit is often referred to as "moment of inertia" or "angular velocity".
