How do you calculate translational angular momentum?

How do you calculate translational angular momentum?

p = m*v. With a bit of a simplification, angular momentum (L) is defined as the distance of the object from a rotation axis multiplied by the linear momentum: L = r*p or L = mvr.

Can a body in translatory motion have angular momentum?

Yes, a body in translatory motion can have angular momentum, unless the fixed point about which angular momentum is taken lies on the line of motion of the body.

What is the relationship between torque and angular momentum?

The torque is defined as the rate of change of angular momentum which is the same as the cross product of the linear force and the distance from the axis. So, the torque is the rate of change of angular momentum.

Is friction an external torque?

No external torques act on the system. The force due to friction produces an internal torque, which does not affect the angular momentum of the system.

How do you know if angular momentum is conserved?

Angular momentum, like energy and linear momentum, is conserved. This universally applicable law is another sign of underlying unity in physical laws. Angular momentum is conserved when net external torque is zero, just as linear momentum is conserved when the net external force is zero.

What is angular momentum measured in?

Appropriate MKS or SI units for angular momentum are kilogram metres squared per second (kg-m2/sec). For a given object or system isolated from external forces, the total angular momentum is a constant, a fact that is known as the law of conservation of angular momentum.

Can angular momentum be converted to linear momentum?

The two conservation laws- linear and angular momentum- are absolutely separate. Neither one can be converted to the other.

Is angular momentum conserved in an elastic collision?

Angular momentum is therefore conserved in the collision. Kinetic energy is not conserved, because the collision is inelastic.

Why can an ice skater increase their angular velocity during a spin without and external force or torque?

Angular Momentum in Figure Skating According to the law of the conservation of angular momentum, the angular momentum of an object will not change unless external torque is applied to the object. So, in order to spin/jump, the skater must generate angular momentum.
