Question

what do you understand by inertia and inertia of direction​

Answer 1

Explanation:

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

Inertia of direction is defined as the inability of a body or object to change its direction ofmotion by itself. That is external force is required to change itsdirection of motion

Answer 2

Inertia

Inertia is a resistance of an object to change in it's velocity and it's motion. The first law of motion is dependent upon inertia. The first law of motion stated that "There is a no change in the position of any object, unless any external unbalanced force acts on it".

Definition of Inertia is also as same as the definition of the first equation of motion. Because, Inertia = First Law of Motion.

• Inertia is a kind of passive property which able or doesn't able to change its position unless any force acts on it.
• If the force acted is balanced force, then there will be no effect.
• Inertia of a body is dependent upon the unbalanced force.

Inertia of direction:

A body travelling in a particular direction at a particular speed cannot change its direction unless any force is being applied on it. The best example of 'Inertia of direction' can be given as:

Rotating wheels water - When the wheels of any vehicle rotate, then we see that, the water attached with them is automatically throughout. This is an example of inertia of direction.

• The property of inertia of direction is related to the concept inertia.
• Inertia is related to the first law of motion.
• Inertia of direction stated that, there is no change in the direction of any object unless any external force is applied on it.
