Q. What is the tendency of a stationary object to remain in its still state or its inability to change its stationary state?
Solution:
Inertia is the inability of an object to change its own state of motion or motion.
Inertia is of two kinds,
- Motion inertia
- Static inertia
Motion inertia is the tendency of an object in motion to remain in motion or to change its motion.
E.g., a runner cannot finish the race as soon as he reaches the finish point.
Static inertia is the tendency of a stationary object to remain in its still state or its inability to change its stationary state.
For example, when the horn of a mango tree is shaken, the mango falls off when it starts to move.
The inertia of an object depends on its mass. Inertia increases as mass increases.
