Question

What do you mean by Inertia ?​

Answer 1

Answer: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.

Explanation:

Answer 2

Intertia :

Inertia is the property of body due to which it it opposes the change in its state .

⇒Inertia of a body is measured by mass of the body.

⇒Interia is directly proportional to mass of the body .

${\purple{\boxed{\large{\bold{inertia \: \propto \: mass \: }}}}}$

Types of interia :

1) Inertia of rest:

It is the inability of a body to change by itself, its state of rest.

⇒Example :

• The dust particles in a blanket fall off when it bitten by a stick.
• When a bus or a train starts suddenly the passengers sitting inside tends to fall backwards etc .

2) Inertia of motion:

It is the inability of a body to change by itself ,it's state of uniform motion.

⇒Example :

• A person jumping out of a running train fall forward
• A ball thrown upwards in a running train continues to move along with the train. etc

3) Inertia of direction

It is the inability of a body to change by itself , it's direction of motion.

⇒Example:

• Rotating wheels of vehicle through out mud , on inner side of muguard over the wheels.
• A body released from a balloon rising up, continues to move in the direction of balloon. etc
