Physics

4. measures the degree to which an object has rotated around a fixed axis, usually expressed in radians or degrees.
6. a quantity that measures an object’s resistance to rotational acceleration, which depends on mass distribution relative to the rotation axis.
9. Rotation Defines the axis as the fixed line around which an object rotates in rigid body motion.
10. a quantity that measures how difficult it is to alter the rotational motion of a spinning object.
11. Measures the angle through which an object rotates, typically expressed in radians.
12. In rotational dynamics, force is what initiates or influences rotation when applied at a distance from the axis.
13. the perpendicular distance between the axis of rotation and the line of action of the applied force.
14. occurs when an object is at rest, meaning the net force and net torque acting on it are zero. This concept is demonstrated using examples like a balanced seesaw.

1. States that, in the absence of external torque, angular momentum remains conserved within a closed system.
2. Explains that work in rotational motion is done by applying torque over a rotational displacement.
3. The study of the forces and torques that cause or change the rotational motion of objects, including concepts like torque, moment of inertia, and angular momentum.
5. Introduces the concept of kinetic energy in rotational motion, calculated using the moment of inertia and angular velocity.
7. The study of the motion of rotating objects, focusing on angular displacement, angular velocity, and angular acceleration without considering the forces causing the rotation.
8. Describes the rate of change of angular velocity.
9. Defines the rate at which angular displacement changes over time.
15. the force that causes rotation, generated when a force is applied at a distance (lever arm) from the rotation axis.
