Linear momentum is the momentum of an object moving in a straight line, while angular momentum is the momentum of an object rotating around an axis. The main difference is the direction of motion - linear momentum is in a straight line, while angular momentum is in a circular motion. This difference impacts the motion of objects by determining how they move and interact with their surroundings. Objects with linear momentum will continue moving in a straight line unless acted upon by an external force, while objects with angular momentum will continue rotating unless a torque is applied to change their direction.

How is torque related to angular momentum and what is the significance of this relationship?

Torque is the force that causes an object to rotate around an axis. Angular momentum is the measure of an object's rotational motion. The relationship between torque and angular momentum is that torque applied to an object will change its angular momentum. This relationship is significant because it explains how forces can affect the rotation of objects, such as in the case of spinning wheels or rotating machinery.


Do all objects have a momentum?

No. An object has momentum only if it is in motion..There are two kinds of momentum: linear momentum(or translational momentum), and angular momentum (or rotational momentum)..Linear momentum is a vector quantity and is calculated as mass x velocity (p = mv). Therefore, if an object's velocity is zero, then it has no linear momentum, but if an object is in motion, then it does have linear momentum..VERY IMPORTANT NOTE: Velocity, and therefore linear momentum, is always relative to the frame of reference. For a more complete discussion about velocity, see the related answer, referenced below, entitled 'How to Find Velocity'..Angular momentum is a pseudovector quantity that describes the momentum of an object that is spinning or rotating in place. An object has angular momentum only when it is spinning, or rotating about an axis. When an object is not spinning or rotating, then it does not have angular momentum..It is possible for an object to have only linear momentum, only angular momentum, or both angular and linear momentum. Note that this discussion falls apart in quantum mechanics, so we are only discussing classical physics - that is, every day observable objects, and not light particles (photons), electrons, or other quantum particles..All objects do have inertia, which is a resistance to a change in its momentum.


What is the applications of angular momentum?

Angular momentum is used in various applications in physics and engineering, such as in analyzing the motion of objects in rotation (like spinning tops or satellites), understanding the behavior of gyroscopes, and explaining phenomena like the conservation of angular momentum in celestial bodies. It is also crucial in quantum mechanics for describing the rotational properties of particles.


Where is angular momentum found?

Angular momentum is a property of rotating objects and is found in systems where there is rotational motion, such as spinning tops, planets orbiting stars, and moving particles with rotational motion. It is a quantity that describes the rotational inertia and velocity of an object around a specific axis.


What has angular momentum?

Angular momentum is a property that objects possess when they are rotating around an axis. It is defined as the product of an object's moment of inertia and its angular velocity. It plays a crucial role in various scientific fields, including physics and engineering.

What does angular mean?

Angular momentum is an expression of an objects mass and rotational speed. Momentem is the velocity of an object times its mass, or how fast something is moving times how much it weighs. Therefore angular momentum is the objects mass times the angular velocity where angular velocity is how fast something is rotating expressed in terms like revolutions per minute or radians per second or degrees per second.

What is an angular momentum?

Angular momentum is a measure of an object's rotational motion, calculated as the product of its moment of inertia and angular velocity. It is a vector quantity, meaning it has both magnitude and direction, and is conserved in the absence of external torques. Angular momentum plays a crucial role in understanding the behavior of rotating objects, such as planets orbiting the sun or a spinning top.


Why is angular momentum used?

In the same way that objects in linear motion tend to remain that way, objects which are rotating tend to keep rotating. Thus, we need both linear and angular (rotational) motion.


How does the concept of angular momentum apply to the motion of a merry-go-round?

Angular momentum is a property of rotating objects that describes how fast they are spinning and how spread out their mass is. In the case of a merry-go-round, the concept of angular momentum explains how the speed and direction of the spinning motion of the ride are affected by the distribution of weight and the force applied to it.


What is angular momentum?

Angular momentum is a measure of an object's rotational motion, determined by the mass of the object, its angular velocity (rate of rotation), and the distribution of mass around its axis of rotation. It is a vector quantity, with both magnitude and direction, and is conserved in the absence of external torques.
