What physical quantities are represented by axial vectors?
Axial vectors represent physical quantities associated with rotational motion, such as angular velocity, torque, and angular momentum. These quantities have both magnitude and direction, and their direction is perpendicular to the plane of rotation.
What is the relationship between the direction of angular momentum and the motion of a rotating object?
The direction of angular momentum is always perpendicular to the axis of rotation of a rotating object. This means that as the object rotates, its angular momentum will also change direction, influencing its motion and stability.
Angular acceleration is it scalar or vector?
Angular acceleration is a vector quantity because it has both magnitude (rate of change of angular velocity) and direction in rotational motion. The direction of angular acceleration aligns with the axis of rotation it is acting upon.
Can a body in translatory motion have angular momentum?
No, a body in translatory motion does not have angular momentum as angular momentum is associated with rotational motion. Translatory motion involves motion along a straight line, while angular momentum involves rotation around an axis.
What is the angle between angular and tangential velocity?
The angle between angular and tangential velocity is 90 degrees. Angular velocity is perpendicular to the direction of tangential velocity in a circular motion.
When angular velocity decreases the direction of angular acceleration is opposite to angular velocity .why?
Take the velocity to be in positive direction. Positive acceleration increases velocity and they are in the same direction. Negative acceleration reduce velocity and they are in opposite direction. It does not matter if the motion in linear or anfular.

What is the physical significance of orbital angular momentum?
Orbital angular momentum refers to the rotational motion of a particle around a fixed point. It is important in quantum mechanics as it quantizes the angular momentum associated with the motion of an electron around the nucleus in an atom. The magnitude and direction of orbital angular momentum affect the energy levels and the spatial distribution of electron clouds in atoms.

The angle between angular and tangential velocity is 90 degrees. Angular velocity is perpendicular to the direction of tangential velocity in a circular motion.
How can you determine the direction of motion?
The direction of motion can be determined by observing the change in position of an object over time. If the position is increasing, the object is moving in the positive direction; if it is decreasing, it is moving in the negative direction. Additionally, the sign of the velocity can indicate the direction of motion: positive for forward motion and negative for backward motion.
Is angular acceleration a pseudo vector?
No, angular acceleration is a true vector quantity because it has both magnitude and direction. It describes the rate at which an object's angular velocity is changing in a rotational motion.
What can have positive or negative value depending on the direction of the change in position?
Velocity can have positive or negative value depending on the direction of the change in position. Positive velocity indicates motion in one direction, while negative velocity indicates motion in the opposite direction.
What is the relationship between angular acceleration and centripetal acceleration in rotational motion?
In rotational motion, angular acceleration and centripetal acceleration are related. Angular acceleration is the rate at which an object's angular velocity changes, while centripetal acceleration is the acceleration directed towards the center of rotation. In rotational motion, centripetal acceleration is caused by angular acceleration, as the change in angular velocity results in a change in direction, causing the object to accelerate towards the center of rotation.
Does linear motion have angular momentum?
I believe that any particle in linear motion must also have some angular momentum because all particles have spin. In the case of a photon the spin, wavelength and angular momentum all vary with the relative linear velocity. So in my point of view time itself is the ratio between relative linear and angular momentum.
