What is the law of inertia for rotation?
The law of inertia for rotation.
Explanation of Solution
Introduction:
Newton's first law of inertia states that an object that is in state of rest or in motion, remains as it is unless an unbalancedexternal force acton the it.This law is also applicable to rotating objects.
The greater the objects rotational inertia, more difficult it is to change its rotational speed. The rotating object tends to remain rotating.
Conclusion:
The resistance of an object to change its rotational motion is known as rotational inertia.
