Question

what is vector quantity​. What is moment

Answer 1

Answer:

Moment of inertia is the property where body resists change in its state of rotatory motion. Inertia is a measure of mass so it is scalar quantity. But an object in rotatory motion will change its direction every point to point . Hence it is also vector quantity.

Answer 2

Explanation:

Torque or moment of force is a vector quantity. ... In other words, vector quantity has both magnitude as well as direction, now we know if we have to apply force we have to do it in some direction, same thing will apply to torque, if you want to apply torque then you need direction
