When an object rotates, its momentum remains constant in magnitude and direction if there are no external torques acting on it. This is known as the conservation of angular momentum. In rotating systems, any changes in the distribution of mass within the system can cause the system to spin faster or slower without any external force being applied.

If something shrinks in size but not in mass what happens to its angular momentum?
Angular momentum is maintained in such a case - and in fact in all cases, unless angular momentum is transferred to, or from, another body. This means it must rotate faster.Angular momentum is maintained in such a case - and in fact in all cases, unless angular momentum is transferred to, or from, another body.

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.
When is the angular momentum of a system not conserved?
The angular momentum of a system is not conserved when external torques are applied to the system. These torques can change the angular momentum by causing the system to rotate faster or slower or by changing the direction of its rotation.
When two cueballs collide what happens to the momentum?
When two cueballs collide, momentum is conserved. This means that the total momentum before the collision is equal to the total momentum after the collision. The cueballs will transfer momentum between them during the collision, but the overall momentum of the system remains the same.
What happens to the momentum if the mass stays the same but the velocity is increased?
If the mass stays the same but the velocity is increased, the momentum of the object will also increase. Momentum is directly proportional to velocity, so an increase in velocity will result in a proportionate increase in momentum.

What happens to the speed of pursued plane when it returns the fire?
When the pursued plane returns the fire, a conservation of momentum in its speed happens. The momentum after the event will be equal to the momentum before the event.
You are riding your bike And you hit a pothole which stops your bike What happens to you and why?
If your front wheel stops abruptly, you'll likely go over the handlebars - the forward momentum will rotate you and the bike over the front wheel.
How is the moon able to rotate?
Everything in the universe (including the moon) has rotational momentum, causing rotation.
Why do neutron stars rotate so much more rapidly than ordinary stars?
Neutron stars rotate rapidly due to their conservation of angular momentum. When a massive star collapses into a neutron star, its core spins faster as it contracts. Since angular momentum is conserved, the neutron star continues to rotate rapidly as a remnant of the collapsed star.
What happens to momentum in an inelastic collision?
Momentum of the system is conserved.Keep in mind kinetic energy of the system is not conserved
If you drop a suitcase out of a car what happens to the cars momentum?
If you drop a suitcase out of a moving car, the momentum of the car will decrease as there will be less mass, therefore less momentum. :)
What happens to the leniar momentum when force is absent?
Nothing. Momentum is mass in kg x velocity in m/s.
What makes the earth to rotate around the orbit?
The Earth condensed out of a rotating Solar Nebula, inheriting its angular momentum for the condensing cloud. The conservation of angular momentum allows the Earth to maintain its orbit.
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.
When is the angular momentum of a system not conserved?
The angular momentum of a system is not conserved when external torques are applied to the system. These torques can change the angular momentum by causing the system to rotate faster or slower or by changing the direction of its rotation.
