Question

define inertia of direction brefily with examples
i will mark as brain list plz

Answer 1

Inertia is the resistance of any physical object to any change in its state of motion. This includes changes to the object's speed, direction, or state of rest. Inertia is also defined as the tendency of objects to keep moving in a straight line at a constant velocity.


example are
Mud through rotating wheels: we have seen that the rotating wheels of a vehicle throughout mud in a tangential direction. This is due to inertia of direction. This is the reason that the mud guards are provided in vehicles over the wheels to stop this mud so that to protect the clothes.

Our protection through umbrella: The second example of inertia of direction is protection of us by umbrella. The rain drops falling vertically downwards cannot change their direction of motion and so cannot wet us when the umbrella is up.

Tangential movement of untied stone: The third example of inertia of direction is the tangential movement of a stone. This happened when a stone tied to one end of a string is whirled and if the string or thread suddenly breaks then the stone flies off along the tangent to the circle. This is due to the reason that the pull in the thread was forcing the stone to move in a circle. As soon as the thread breaks, the pull vanishes. The stone in a bid move along the straight line moves tangentially due to inertia of direction.

Answer 2

The first law of motion stated that a body of mass remains steady at rest or in straight line in motion and this is the inertia that resist the change in kinetic energy and so to change kinetic energy of the body or motion of the body it reqires a force acts upon the body directly or indirectly internally or externally.
e.g.......... The passenger in a running bus tends to lean forward when the bus stops suddenly
When the bus is running, the whole body of the passenger is in the state of motion When the bus stops suddenly the lower part of the passengers body which is in contact with the bus comes to rest. But the passengers upper portion remains in the state of motion due to the inertia of motion This is the reason for the passenger to lean forward when the bus stops suddenly
