Question

What is Inertia??? ​

Answer 1

Answer:

INERTIA:

It is the inherent property of mass due to which any body remains in the same state ( rest or motion ) .

Explanation:

TYPES OF INERTIA:

There are 3 types of inertia:

• Inertia of rest -

If a body is in rest it will tend to be in rest until the external

force is applied.

Example: if a stone is lying on the floor it will need external

force to gain motion.

• Inertia of motion -

If a body is in motion it will tend to be in motion until the

external force is applied.

Example: If a bicycle is moving it will need external force to

stop.

• Inertia of direction -

If a body is moving in a particular direction it will tend to

move until the external force is applied.

Example: If a tyre is moving the dirt will be thrown

tangentially backward or forward in a particular

direction.

LAWS OF INERTIA:

Net external force on a body is zero.

Then the velocity of centre of mass will remain constant.

Answer 2

• Inertia is the resistance of any physical object to any change in its velocity.
• This includes changes to the object's speed, or direction of motion.
• An aspect of this property is the tendency of objects to keep moving in a straight line at a constant speed, when no forces act upon them.
