Question

Rank the following in terms of increasing inertia:

Answer 1

C. A 1200kg car is going 15m/s

Answer 2

Answer:

Increasing order of inertia is as following

d) <  b)  <  c)  < a)

Explanation:

Inertia is the property of mass. We define inertia as the property of mass due to which a given mass will will resist any change in it state of motion.

So if an object will have more mass then it is more difficult to change the state of motion of that type of object.

So here we have

a). A 10,000 kg train car at rest  

b). A 100 kg person running at 5 m/s  

c). A 1200 kg car going 15 m/s  

d). A 15 kg meteor going at a speed of 1000 m/s

Now for arranging increasing order of inertia we need to arrange them in increasing order of their mass

d) <  b)  <  c)  < a)

So above is the increasing order of inertia
