Define the term inertia and its types. A ball and a car, which one has greater inertia?
The unwillingness of a particle or an object to change its state of rest or uniform motion along a straight line by itself is called inertia.
There are three types of inertia:
- Inertia of rest
- Inertia of motion
- Inertia of direction
Since, inertia ∝ mass of the objects
As we know, Mball << Mcar
Thus, the car has greater inertia.
