The inertia of rest is the property of a body to resist change in motion when the object is in rest. When a body is at rest, it has certain inertia of rest according to its mass and it is difficult to make it move immediately. The object moves only after a certain force is applied. For example, When we are on a roller coaster and we start from a position of rest and come down quickly then we tend to move backward rather than forward. This is due to the inertia of motion we try to maintain our position of rest.

When we dust cloth or a carpet, we shake it off vigorously. What we are doing actually is setting the carpet into motion. But, the dust particles due to inertia of motion, don’t move along with the carpet, they try to retain their original position. Hence, they get separated from the carpet or cloth.
When we stick out a balloon from our cars that is in motion, we can see that the balloon moves backward. The balloon tries to be at rest due to the inertia of rest.
You might have observed this example of inertia of rest as a kid. A coin is placed on top of cardboard which is placed over a glass. The carboard is pulled quickly to ensure that the coin falls into the glass due to inertia of rest.
When we pull off the sticky tape immediately then nothing much happens. But, if we pull slowly then the part of the object to which it was stuck may come off. When we remove immediately then due to inertia of rest the object remains at its state of rest and does not move much.
