Momentum is to force as angular momentum is to what?
Torque
When there is no external force acting on a body , which physical quantity is conserved?
Angular Momentum. The conserved quantity we are investigating is called angular momentum. The symbol for angular momentum is the letter L. Just as linear momentum is conserved when there is no net external forces, angular momentum is constant or conserved when the net torque is zero.
What equations link angular and linear momentum If you exert a force on a free floating body it will have angular and linear momentum In what proportions and how are they linked?
angular momentum = linear momentum (of object) x perpendicular distance (from origin to the object) where x stands for cross product. angular momentum = mv x r (perpendicular dist.)
What is torque when angular momentum is constant?
When angular momentum is constant, torque is zero. This means that there is no net external force causing the object to rotate or change its rotational motion. The law of conservation of angular momentum states that if no external torque is acting on a system, the total angular momentum of the system remains constant.
For motion under central force angular momentum equals?
constant
Which force acts for the revolution of the earth in its own axis?
no force, just angular momentum which is conserved.
Angular momentum is a measure of?
angular momentum is the measure of angular motion in a body.
Why pulling your arms in causes you to go faster?
When you are spinning there is a force called angular momentum that keeps you spinning and the angular momentum forms a ratio with the size of the object that is spinning so as you bring your arms inward, your size decreases increasing your angular momentum which spins you faster.
What keeps Venus up in space?
Angular momentum is what keeps the planet Venus up, in the sense of not falling into the sun. To be precise, it is the balance between the gravitational attraction of the sun, and the angular momentum of the planet, which keeps Venus in its orbit.
Is the angular momentum of a body which is under the action of central forces is constant?
Yes, the angular momentum of a body under the action of central forces is constant. Central forces act along the line connecting the center of force and the body, which means they do not exert a torque about the center of force. As a result, the angular momentum, which depends on both the position and linear momentum of the body, remains conserved in such systems.
How do you calculate angular momentum in a rotating system?
Angular momentum in a rotating system is calculated by multiplying the moment of inertia of the object by its angular velocity. The formula for angular momentum is L I, where L is the angular momentum, I is the moment of inertia, and is the angular velocity.
If Jupiter underwent gravitational collapse what would happen to its rate of rotation?
It would increase due to the conservation of angular momentum.
