Question

Define dynamic inertia with example

Answer 1

Answer:

Explanation:

I suspect the person who used the term ‘dynamic inertia’ is thinking of Newton’s first law and how something is thing which is moving tends to remain moving.It is a pointless differentiation because what is static inertia to one person is dynamic inertia to another depending on gthe motion of the observer.

Finally the person may be thinking of the degree of resistance to change in motion. Newtons 2nd Law. F= ma.

If this is what they mean by dynamic inertia, they should simply use the same word as everybody else! - mass. Many people seem to thinbk inertia is like mass but they cant tell you if they are exactly the same or what the differecne is. THe truth is they have vague ideas- these are no good at all in science. You can get by more than perfectly well in science by not using the word inertia at all!

PS ( Moment of’ inertia’ is different - it is badly named - but it is more the angular equivalent of mass.)

Answer 2

There is no such thing in science. In everyday language people can put words together however, they feel.

Inertia means ‘to not change’. We sometimes use the word inertia to describe the way velocity of an object does not change without an external force. But you cant have an amount of imnertia and you cant really have dynamic inertia which seesm to imply some idea of movement and no change.
