Find Angular Momentum.
How to find velocity of a particle.
The Attempt at a Solution
If i differentiate with `dt` both sides, I'm getting velocity y-component=velocity x-component.
Then i feel helpless
what are you differentiating and why? You already know the velocity.LoveBoy said:
Angular momentum is a physical quantity that describes the rotational motion of a particle or object around an axis. It is a vector quantity, meaning it has both magnitude and direction.
Angular momentum is calculated by multiplying the mass of the particle by its velocity and the distance from the axis of rotation. It is represented by the symbol L = mvr, where m is the mass, v is the velocity, and r is the distance from the axis.
Angular momentum is a measure of rotational motion, while linear momentum is a measure of linear motion. Both quantities are conserved in a closed system, but angular momentum takes into account the distance from the axis of rotation, while linear momentum does not.
The greater the angular momentum of a particle, the more stable it is. This is because a particle with a larger angular momentum has a greater tendency to maintain its rotational motion, making it more resistant to external forces that may try to change its direction or speed.
Yes, angular momentum can be changed by external torques acting on the particle. These torques can cause the particle to speed up or slow down, or to change the direction of its rotational motion. However, the total angular momentum of a closed system will always remain constant.
