Hmm...angular velocity. First of all, when you talk about the universe, it seems like you are talking about an object. But the universe is a rapidly expanding object of space and time, so there should be no real boundaries. That means it can't really rotate at all. So, in conclusion, using angular velocity is not suitable for measuring what you are trying to find.
What else can I help you with?
Where is the closest zero gravity place?
There is no "zero gravity" place. Gravity permeates all the universe. Astronauts in orbit are often said to be in zero gravity but they are, in reality, on a position where their orbital velocity balances the attraction of the Earth.
If a satellite's radial velocity is zero at all times its orbit must be elliptical or parabolic?
Not necessarily. A circular orbit around a central body, such as a planet, would also have a radial velocity of zero at all times. In a circular orbit, the satellite's velocity vector is always perpendicular to the radius vector, resulting in a constant radial velocity of zero.
Can you bring a spaceship to a halt in space?
In principle, yes; but please note that:* There is no such thing as an "absolute velocity". You need to specify that it has zero velocity with respect to some other object. In other words, that it should move at the same velocity as that other object. As Earth, for example.* An object won't stay at such a relative velocity of zero for long. Forces, and mainly gravitational forces, will soon change its velocity. For instance, if you have a spacecraft that is in orbit around Earth, and you make it halt, it will fall straight down. (In this case, it is precisely its speed that keeps it in orbit.)
Does a solar nebula spin?
Almost certainly. As the dust and gas fall into the nebula under its gravity, each atom will impart SOME sort of sideways momentum, and the total of all that is almost certainly not zero; there will be some angular momentum.
Why a skydiver falls towards earth even when he is under the influence of balance forces?
"Balanced forces" doesn't mean that an object doesn't move. "Balanced forces" means that the vector sum of forces on an object is zero. Now, according to Newton's First Law, if no force is acting on an object, if that object is at rest it will continue being at rest; if it is moving, it will continue moving with the same velocity. In other words, there will be no CHANGE in velocity; that doesn't mean that the velocity must necessarily be zero.
Can stationary have non zero angular acceleration?
No, an object is considered stationary when it has zero velocity and zero acceleration. Angular acceleration refers to the rate at which an object's angular velocity changes over time. If something has a non-zero angular acceleration, it means that it is rotating at a changing rate.
Can a stationary object have a non zero angular acceleration?
No, a stationary object cannot have a non zero angular acceleration. Angular acceleration is a measure of how an object's angular velocity changes over time, so if an object is not rotating, its angular acceleration is zero.
What happens when moments are unbalanced or balanced?
When moments are unbalanced, it means that there is a net torque acting on an object, causing it to rotate. This can result in rotational motion or change in angular velocity. When moments are balanced, the total torque acting on the object is zero, resulting in either no rotation or constant angular velocity.
What is the angular velocity of the wheel before braking began if the wheel rotates through 6 radians in 2 seconds as it is uniformly brought to rest?
It was 6 radians per second. Angular acceleration = -3 radians per second2 Initial angular velocity = 6 radians per second. Final angular velocity = zero. Average angular velocity = 3 radians per second. Angular displacement in 2 seconds = 3 x 2 = 6 radians.
Is it true that if the total angular momentum of a system of particles is zero, then all the particles are at rest?
No, it is not necessarily true that if the total angular momentum of a system of particles is zero, then all the particles are at rest. The total angular momentum being zero means that the rotational motion of the system is balanced, but individual particles within the system can still have their own angular momentum and be in motion.
What are the magnitude of the angular velocity and the angular accelaration of the second hand of a clock?
-- The angular velocity isone revolution/minute = 360 degrees/minute = 6 degrees/second .(2 pi) radians/minute = pi/30 radians per second . -- If the clock is working properly ... not starting, stopping, speeding up, orslowing down ... then the angular acceleration of any of its hands is zero.
What is the Conditions for angular acceleration equal to zero?
Angular acceleration is equal to zero when an object is rotating at a constant angular velocity without any change in its rotational speed. This occurs when the net torque acting on the object is zero, meaning that there are no external forces causing the object to accelerate or decelerate rotationally.
What is the angular velocity of a 6 and ndashfoot pendulum that takes 3 seconds to complete an arc of 14.13 feet Use 3.14 for and pi.?
The whole point of a pendulum is that is swings back and forth. It does not travel at constant angular velocity: the angular velocity is zero at the two ends of its arc and it reaches a maximum when the pendulum is vertical. Consequently there cannot be a sensible answer to the question as asked.The average angular velocity, which is an entirely different measure, is 45 degrees per second.
Can a particle in one dimensional with zero speed may have non zero velocity?
No, a particle in one dimension with zero speed will have zero velocity. Velocity is a vector quantity that includes both the speed and direction of motion, so if the speed is zero, the velocity will also be zero since there is no direction of motion.
Can you have a zero velocity?
Yes, an object with zero velocity is either at rest or has come to a complete stop. Velocity is a vector quantity that indicates both speed and direction of motion, so a zero velocity means the object is not moving.
Can constant velocity be zero?
Yes. Zero velocity is a velocity; if it is always zero then it is a constant velocity.
What is the velocity if you travel in 10 mile circle at 15 mph and end up where you started?
The velocity is zero because the total displacement vector is zero.
