What is the dimension of angular momentum?
Angular momentum is a vector quantity and therefore has dimensions of mass multiplied by length squared divided by time. In SI units, the dimension of angular momentum is kg * m^2/s.
Dimension of angular momentum?
case 1 is mass (m) on weightless length (r) of string at constant velocity (v), so angular momentum L = r * (m * v), SI units are n.m.s. or kg.m^2.s^-1 . case 2 is mass(m) rotating around an axis inside its own mass ie solid sphere rotating about its fixed symmetry axis, angular momentum L = I * w, where I is the mass moment of inertia of the sphere about its fixed symettry axis, and w is the rotation in radians per second, units are kg.m^2 for I, and rad / sec for w
What is Linear momentum measured in?
Linear momentum of an object is its mass times its velocity. Since momentum does not have a unit name of its own its units are whatever you use for mass & velocity. The SI units would be Kg-M/S . The cgs units would be gm-cm/S , and the English units would be Slug-Ft/S . It can also be expressed in terms of force units. SI: Newton-Sec. , Cgs :dyne-Sec, English: Pound-Sec.
What are the units of momentum called?
Momentum is the product of mass times velocity, so in SI units, the units are kilograms x meters / second. There is no special name for this unit.
What are the units for momentum?
The formula for momentum is (mass)*(velocity), so the SI units would bekg m sec-1 or kg-m/sec
What is the dimension of angular momentum?
Angular momentum is a vector quantity and therefore has dimensions of mass multiplied by length squared divided by time. In SI units, the dimension of angular momentum is kg * m^2/s.
What is unit of angular momentum?
Angular momentum is defined as the cross product of a distance (from the axis of rotation) and a momentum, so you have to use units accordingly. In the SI, that would be meters x kilograms x meters / second, which you can simplify to meters squared x kilograms / second. This is equivalent to joules x seconds.

What is momentum and state its SI unit?
Momentum is mass * velocity. Its units, in the SI system are kilogram metre per second

What is the constant of proportionality between torque and angular acceleration?
The rotating object's moment of inertia. Similar to Newton's Second Law, commonly quoted as "force = mass x acceleration", there is an equivalent law for rotational movement: "torque = moment of inertia x angular acceleration". The moment of inertia depends on the rotating object's mass and its exact shape - you can even have a different moment of inertia for the same shape, if the axis of rotation is changed. If you use SI units, and radians for angles (and therefore radians/second2 for angular acceleration), no further constants of proportionality are required.
What is the unit measurement for monemtum?
Linear momentum is (mass)*(velocity)[a vector mv], so the SI unit would be kg*m/s, angular momentum is the sum of all resultant vectors of r x mv for each point on a spinning object, and would have units kg*m2/s
If you are given the mass of an object in pounds the time in seconds and the distance in feet what must you do before you can calculate the momentum in SI units?
You must convert the mass from pounds to kilograms, time from seconds to seconds, and distance from feet to meters. Only then can you use the formula for momentum (momentum = mass * velocity) to calculate momentum in SI units (kg*m/s).
What is the unit of angular displacement?
Radian is the unit for angular displacement is SI system of units.
Why does momentum have no designated SI unit name?
Momentum is a vector quantity, calculated as the product of an object's mass and velocity. Its SI unit is kilogram meters per second (kg m/s), which represents the combination of mass (kg) and velocity (m/s) in defining momentum. Momentum does not have a separate designated unit name because it is derived from fundamental SI units.
