There are actually 3 kinds of inertia. They are as follows :
1. Inertia of Rest
2. Inertia of Motion
3. Inertia of Direction
But nowadays people consider that there are 2 kinds of inertia , inertia of rest and inertia of motion.
There is no "A inertia." Its just inertia and inertia is the measure of an objects to stay at rest or to keep moving.
Inertia is the tendency of all objects to resist change in motion.
Inertia is the resistance of motion of an object. The more inertia, the harder it is to move something. The less inertia, the easier it is to move. Take a bowling ball and a marble. The marble can be flicked by the finger, because it has less inertia. The bowling ball takes the entire hand because it has more inertia than the marble. According to Newton's laws, an object that is moving tends to continue in motion. A moving object has inertia as it has Mass and Velocity. An object that is not moving requires a Force exerted on the Mass to start it moving.
Inertia can be demonstrated like this: A car is driving, the driver takes his foot off of the gas and the car keeps going although there is no force pushing the car. Inertia is what keeps the car going.
Not a single body is present in this universe without mass but they can be weight less.By definition, mass is the measure of the inertia of a body, so if the body were without mass (as some particles, for example), it would have no inertia.
Inertia and Earth's gravitational pull
Friction - several different kinds - and inertia. If riding uphill, also gravity.
It is due to inertia. Inertia is characteristics of matter. There are three kinds of inertia. One is inertia due to rest. Second one is inertia due to motion. Third is inertia due to direction. The question asked is concerned with inertia due to rest. Inertia is defined as the inability of matter to change by its own its state of rest or of uniform motion along a straight line.
Inertia is a property of matter. It is the tendency of an object to resist changes in its state of motion. It does not originate from a force itself, but rather describes how objects behave in relation to external forces applied to them.
Resting Inertia and Moving Inertia
Yes, air has inertia which is the tendency of a moving object to keep moving in a straight line unless acted upon by an external force. This property of air is why it takes time for air to start moving or stop moving when a force is applied to it.
There is no "A inertia." Its just inertia and inertia is the measure of an objects to stay at rest or to keep moving.
Inertia
Resistance to the motion of an object is friction. Several different kinds of friction exist, including dry, fluid, lubricated, skin, and internal.
The three types of inertia are inertia of rest, inertia of motion, and inertia of direction. Inertia of rest is the tendency of an object to remain at rest. Inertia of motion is the tendency of an object to continue moving at a constant velocity. Inertia of direction is the tendency of an object to resist changes in its direction of motion.
