WebPhysics questions and answers. Question 3- A rigid body rotates about a fixed axis with a constant angular acceleration. Which one of the following statements is true concerning … WebAngular momentum is rotational momentum that is conserved in the same way that linear momentum is conserved. For a rigid body, the angular momentum (L) is the product of the moment of inertia and the angular velocity: L = I ω. For a point of mass, angular momentum can be expressed as the product of linear momentum and the radius ( r ): L = mvr.
WebApr 7, 2024 · Angular acceleration simply refers to the time rate of change of the angular velocity. It should be noted that the angular acceleration is also known as rotational acceleration. The angular acceleration is simply the quantitative expression for the change in the angular velocity per time. When a rigid body rotates about a fixed axis, all the ...
