Question

does inertia depends on speed or mass ​

Answer 1

Answer:

True

Inertia is that quantity which depends solely upon mass. The more mass, the more inertia. Momentum is another quantity in Physics which depends on both mass and speed.

This is your answer.

Answer 2

Yes

Inertia is the natural phenomena to resist any change in an object's state of motion or rest. It can be also defined as 'the measurement of an object's mass'.

• The more an object's mass, the more it's inertia and similarly, the less an object's mass, the less it's Inertia.
• The speed of an object determines it's inertia of motion.

More: It's SI unit is $kg$. Moreover, it can be classified as,

1. Static inertia, &
2. dynamic inertia.
