Moment Of Inertia & Angular Momentum

Question 1

The greater the _______, the more _____ is required to produce angular acceleration.

Answer 1

-Moment of inertia
-torque

Question 2

A body rotates around a fixed axis outside the body.

Answer 2

Circular motion

Question 3

The body’s rotating axes are inside the body.

Answer 3

Rotational motion

Question 4

The body’s rotating axes are inside the body.

Answer 4

Rotational motion

Question 5

refers to the angle at which an object is oriented relative to a reference direction or point. It is a measure of how far an object has rotated or moved around a circular path compared to a defined starting position.

Answer 5

Angular position

Question 6

is a measure of how quickly an object rotates or revolves around a central point or axis. It describes the rate at which the angular position of an object changes over time

Answer 6

Angular velocity

Question 7

is a measure of how quickly the angular velocity of an object changes over time. It describes the rate at which an object speeds up or slows down its rotational motion.

Answer 7

Angular acceleration

Question 8

is a fundamental concept in physics that describes the rotational equivalent of linear momentum. It helps to understand the motion of objects that are rotating or revolving around an axis.
