What else can I help you with?
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.
Is angular momentum a vector quantity?
Yes, angular momentum is a vector quantity because it has both magnitude and direction.
What is momentam?
The moment of linear momentum is called angular momentum. or The vector product of position vector and linear momentum is called angular momentum.
Is angular momentum a vector quantity?
Angular momentum is a vector quantity. Angular velocity, which is a vector quantity, is multiplied by inertia, which is a scalar quantity.
What is the relationship between angular momentum and the cross product in physics?
In physics, angular momentum is related to the cross product through the formula L r x p, where L is the angular momentum, r is the position vector, and p is the linear momentum. The cross product is used to calculate the direction of the angular momentum vector in rotational motion.
How the direction of angular momentum is given by right hand rule?
Angular momentum = r x p... That is position vector r, CROSSED (not multiplied) with momentum vector p. So, to find out the direction the angular momentum will act, take ur right hand, point your fingers in the direction of r, and "curl" (close/bend whatever u wanna call it) ur FINGERS (not thumb) towards p. New, whichever way ur thumb points, that is the direction of the angular momentum Hope that helped
A mass m is moving with a onstant velocity parallel to x axis itts angular momentum with respect to origin is.?
The angular momentum of the mass m with respect to the origin, in this case, would be zero. This is because the mass is moving parallel to the x-axis, so its position vector relative to the origin does not change with time. As angular momentum is defined as the cross product of the position vector and the linear momentum, and in this case, the position vector does not change, the angular momentum is zero.
What is the formula for calculating the angular momentum about a point in a system?
The formula for calculating the angular momentum about a point in a system is L r x p, where L is the angular momentum, r is the position vector from the point to the object, and p is the linear momentum of the object.
Is infinitesimal angular momentum a vector?
Yes, infinitesimal angular momentum is a vector quantity. It has both magnitude and direction, representing the rotational motion of an object. In the context of calculus and physics, infinitesimal quantities are used to describe changes in vector quantities over infinitesimally small intervals.
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.
What is an angular momentum?
Angular momentum is a measure of an object's rotational motion, calculated as the product of its moment of inertia and angular velocity. It is a vector quantity, meaning it has both magnitude and direction, and is conserved in the absence of external torques. Angular momentum plays a crucial role in understanding the behavior of rotating objects, such as planets orbiting the sun or a spinning top.
How would momentum be considered a vector?
Momentum is a vector quantity because it has both magnitude and direction. In physics, momentum is defined as the product of an object's mass and its velocity, and its direction is always the same as the direction of the velocity of the object. As a result, momentum is treated as a vector with both magnitude (the amount of momentum) and direction.
