Question

does mass of any object depend on velocity​

Answer 1

Answer:

Mass, according to the modern definition, does not depend on velocity. It is an invariant quantity.

Answer 2

Answer:

Yes, it depends on velocity but in some special cases only.

Explanation:

Yes because for a lot of time people thought that mass is the measure of content a body has but after coming of the Newton's Second Law of Motion and the popular equation $F=ma$, we learnt that mass is actually the the measure of inertia a body possesses and vary inversely with acceleration. Now let's take an example :

When a body reaches the velocity of light (i.e. 300000 km/s), it's acceleration increases drastically and so it's mass reduces drastically.

Hope you would have understood that mass isn't always invariant and how it can be changed by changing velocity.
