The direction of angular displacement along the axis of rotation is defined by the right-hand rule, where curling the fingers of your right hand in the direction of rotation allows your thumb to point along the axis. This convention helps establish a consistent reference for angular measurements in physics. It provides clarity in determining the orientation of rotational motion, facilitating calculations and understanding in various applications, such as mechanics and dynamics.
What else can I help you with?
The angular velocity vector of earths rotation points from?
Without looking it up, I'll go out on a limb here and state my guess. (Then somebody else can come along and show that my guess was all wet.) I think angular velocity and acceleration are both right-hand-rule guys, with vectors formed by (R) cross (rotation direction). If true, and rotation is from west to east (counterclock viewed from above the north pole), then the angular velocity vector points into the south pole and out of the north pole. Correction: You have stated the true method for the answer above, but got the opposite answer. Since the earth rotates in a counter-clockwise direction viewed from the north pole, the angular velocity vector would point from the center of the earth to the north pole. It's magnitude would be the angular velocity of the earth's spin. -J I think that's exactly what I said ... " ... out of the north pole". Ah I see, my apologies. I think where I was confused was where you stated "into the south pole..." Instead you can state that it would originate from the center and point towards the north pole. You can rewrite it and delete our discussion :)
What are the two kinds of acceleration?
The three basic types of acceleration is absolute (acceleration in a direction), angular (acceleration due to rotation) , and Coriolis (acceleration due to a point changing its distance from the center of rotation while spinning Eg. swirling toilet water.) Hope this helps, Speeding Up, Slowing Down, and Changing Direction
How do you increase the angular velocity of a rotating object?
Angular velocity just means how fast it's rotating. If youaa want more angular velocity, just rotate it faster or decrease the radius (move it closer to the center of rotation). Just like force = rate of change of momentum, you have torque= rate of change of angular moment Or We can increase the angular velocity of a rotating particle by applying a tangential force(i.e. accelaration) on the particle. Since the velocity of the particle is tangential with the circle along which it is moving, the tangential accelaration will not change the diriction of the velocity(as angle is 0),but will cause a change in magnitude. Thus angular velocity will increase.
What is the direction of mercury's rotation?
Mercury, just as Earth rotates alone its axis. The spin is from left to right along this axis with one rotation lasting nearly 176-days on Earth. Needless to say it is a very slow spin in comparison.
What is the offset that occurs along a fault?
The offset along a fault is the distance by which one side of the fault has moved in relation to the other side. This movement can be horizontal, vertical, or a combination of both, and it is a measure of the displacement that has taken place along the fault.
What is the direction of angular acceleration?
Angular acceleration is a vector quantity that points along the axis of rotation according to the right-hand rule. This means if you curl the fingers of your right hand in the direction of rotation, your thumb points in the direction of angular acceleration.
What is the direction of angular momentum?
Angular momentum of a rotating particle is defined as the moment of the linear momentum of the particle about that axis.It is perpendicular to the plane of rotation and parallel to the axis of rotation.
Is the direction of angular velocity same as that of angular momentum when agular velocity is decreasing?
Yes, suppose a body is rotating anti-clockwise, then its angular velocity and angular momentum, at any moment are along axis of rotation in upward direction. And when body is rotating clockwise, its angular velocity and angular momentum are along axis of rotation in downward direction. This is regardless of the fact whether angular velocity of the body is increasing or decreasing.
What is the difference betweentangential velocity or angular velocity?
angular velocity s the rotational analague of linear velocity...direction of linear velocity s along tangent to the circle while that of angulr velocity s along the axis of rotation.the direction of angular v can be find by right hand rule which state that if the axis of rotation s held n right hand with fingers curled round the direction of rotation then the thumb will mark the direction of angular velocity.... the magnitude of angular velocity that s the angular speed is represented by the length of the line along the axis of rotation...its units are rad/sec,degrees/sec or revolution/sec while that of linear velocity s m/sec...
Is a torque vector quantity?

What movement turns a bone along an axis?
Rotation is the movement around a longitudinal axis.
Resolve a displacement of 700 cm into two components along direction lines that lie on opposite sides of the displacement and each of which makes an angle of 30 with the displacement?
no answer
Is there any example of motion where distance and displacement are same?
Yes, if an object moves along a straight path in a single direction without reversing its direction, then its distance and displacement will be the same.
What is the definition of translatory motion with diagrams?
Translatory motion is the type of motion in which an object moves along a straight line. This motion involves all parts of the object moving in the same direction by the same distance. In a diagram, translatory motion can be represented by showing an object changing its position along a single axis without any rotation or angular displacement.
What is the distance and direction of an object from the starting point called?
The distance and direction of an object from the starting point is called displacement. Displacement is a vector quantity that represents the straight line distance between the initial and final position of an object, along with the direction from the starting point to the endpoint.
What is a phase shifting transformer?
This applies to three-phase transformer connections. 'Phase shift' or 'angular displacement', is defined as 'the angle by which the secondary line-to-line voltage lags the primary line-to-line voltage'.Angular displacement depends on the type of transformer connection. The most common are:delta/delta results in an angular displacement of 0o or 180owye/wye results in an angular displacement of 0o or 180odelta/wye results in an angular displacement of 30o or 210owye/delta results in an angular displacement of 0o or 180oThe angular displacement for all possible combinations of three-phase transformer connections are listed in transformer vector group charts.Angular displacement determines whether or not it would be possible to parallel different types of three-phase transformer connections. For example, from the above data, it would be impossible to parallel, for example, a delta/delta transformer with a delta/wye transformer.
Is costheta is a vector?
No. Cos theta (Cos θ) is a trigonometric function. A vector is any physical quantity which has both magnitude and direction. For example, Displacement. Displacement has a magnitude like 240m or 0 or 13 m, etc. It also depends on the direction. If an object moves along the positive direction of x-axis, then the displacement will have a positive sign and if it moves along the negative direction of x-axis, then displacement will be negative. Thus, it has both direction and magnitude and so is a vector. Cos theta is a trigonometric function, strictly speaking.
