what is the difference between angular and linear momentum?
42146
Angular momentum is inertia of rotation motion. Linear momentum is inertia of translation motion. The big difference is that the type of motion which is related to each momentum is different. It is important to consider the place where the force related to rotation applies, which is appears as 'r' in the formula.

Orbital angular momentum is the component of angular momentum. It is the value of angular momentum of the electron revolving around the orbit and the fact that electron is spinning around its own axis is neglected. Angular momentum comprises of orbital and spin angular momentum.

Angular velocity is the rate of change of the angular displacement over time. Angular velocity multiplied by the radius of movement yields the instantaneous linear velocity of theobject. Linear velocity is measured in meters per second, while angular velocity is measured in radians per second.

Two pi radians equals 360 degrees. The angular displacement is not a length (not measured in meters or feet), so an angular displacement is different than a linear displacement. ... As the object rotates through the angular displacement phi, the point on the edge of the disk moves distance sa along a circular path.

Angular acceleration is the change in angular velocity divided by time, while tangential acceleration is the change in linear velocity divided by time. People sometimes forget that angular acceleration does not change with radius, but tangential acceleration does.

No, angular acceleration and radial/centripetal acceleration are two different things. Angular acceleration is the rate at the which the angular velocity changes. Angular velocity is the angular displacement covered over a time interval. ... It is this acceleration that we call the centripetal or radial acceleration.

Linear momentum is defined as the product of mass of a body and its velocity. So dimensions of linear momentum are dimensions of mass times velocity= dimensions of ( m × v)= M L T^-1 .

Angular Speed Formula. Angular speed is the rate at which an object changes its angle (measured) in radians, in a given time period. ... Angular speed and angular velocity use the same formula; the difference between the two is that Angular speed is a scalar quantity, while angular velocity is a vector quantity.

Angular and linear velocity have the following relationship: v=ω×r v = ω × r . As we use the equation of motion F=ma to describe a linear motion, we can use its counterpart τ=dLdt=r×F τ = d L dt = r × F , to describe angular motion.

Angular acceleration separates itself from the others: 1) Because it is an angular quantity, whereas the other two are linear quantities. ... No centripetal acceleration means the object is not moving in a circle. o Centripetal acceleration results from the change in direction of the tangential velocity.

In physics, angular momentum (rarely, moment of momentum or rotational momentum) is the rotational equivalent of linear momentum. It is an important quantity in physics because it is a conserved quantity—the total angular momentum of a closed system remains constant.

Angular momentum applies similarly to rotation of a body. A spinning top continues to rotate due to its angular momentum and heavier the top higher the angular momentum. Torque is the equivalent of force for rotational motion. Torque can be described as a twisting force that causes rotation.

The magnitude of the angular momentum of an orbiting object is equal to its linear momentum (product of its mass m and linear velocity v) times the perpendicular distance r from the centre of rotation to a line drawn in the direction of its instantaneous motion and passing through the object's centre of gravity, or ...

Linear velocity is speed in a straight line (measured in m/s) while angular velocity is the change in angle over time (measured in rad/s, which can be converted into degrees as well).

Angular momentum is measured in kilogram meters squared per second. ... Linear momentum is mass multiplied by velocity, so it follows that angular momentum is the moment of inertia, measured in kilogram meters squared, multiplied by angular velocity, measured in radians per second.

They are both related to an object's velocity (or speed) and mass, but momentum is a vector quantity that describes the amount of mass in motion. Kinetic energy is a measure of an object's energy from motion, and is a scalar.
