what are the types of inertia. give 2 examples for each of then . on what factor does inertia depend
Answers
There are three types of inertia :-
1) Inertia of rest:-
Example - A book lying on a table.
2)Inertia of motion
Example - a moving car on a road
3) Inertia of direction
Inertia is depend on mass of an object
Answer:
INERTIA - If the body is in rest it wants to be in rest, if body is in motion it wants to be in motion until the external force is applied on it.
Inertia is directly proportional to the mass of the body or objects. if body have more mass than more inertia and if less mass than less inertia.
Types of inertia
- Inertia of motion
- Inertia of rest
- Inertia of direction
Inertia of motion--if the bodies in motion it wants to be in motion until the external force is applied on it.
example-
One's body movement to the side when a car makes a sharp turn. Tightening of seat belts in a car when it stops quickly. A ball rolling down a hill will continue to roll unless friction or another force stops it.
Inertia of rest-- if the body is in rest it wants to be in this until the external forces applied on it.
example-One's body movement to the side when a car makes a sharp turn. Tightening of seat belts in a car when it stops quickly. A ball rolling down a hill will continue to roll unless friction or another force stops it.
Inertia of direction-- every object and body in this universe is wants to be in particular direction of its motion or rest until the external force is applied on it.
example-When an object is placed on top of a running bus and the bus takes sudden turn then the object placed on the top of the bus will thrown out in opposite in direction of turning bus. Examples of Inertia of Motion: This is due to inertia of motion.
