Inertia of rest refers to the property of an object to resist changes in its state of rest. Here are four examples that demonstrate the concept of inertia of rest:
1. Pushing a stationary car: When a car is at rest, it requires a significant amount of force to set it in motion. This is because the car's inertia of rest resists any change in its state of rest. Once the car is in motion, however, it tends to stay in motion unless acted upon by an external force.
2. Opening a sticky jar lid: If you encounter a tightly closed jar lid, you may try to open it by twisting. Initially, the lid may resist your efforts due to its inertia of rest. However, as you apply force and overcome the initial resistance, the jar lid starts moving, and then it becomes easier to continue opening it.
3. A book remaining on a table: When a book is placed on a table, it remains at rest until an external force, such as someone pushing or lifting it, is applied. The book's inertia of rest prevents it from moving on its own.
4. A coin on a sheet of paper: If you place a coin on a sheet of paper and quickly pull the paper out from underneath, the coin tends to stay in its original position due to its inertia of rest. This demonstration is often referred to as the "tablecloth trick" and illustrates the concept of inertia.
In all of these examples, objects at rest tend to remain at rest unless acted upon by external forces. This behavior is a result of their inertia of rest.
Answers & Comments
Answer:
Sure! Here are four examples of inertia of rest:
1. When a book is lying on a table and remains there until someone or something moves it.
2. A stationary car staying in place until a force is applied to make it start moving.
3. A ball at rest on the ground that doesn't move until someone kicks or throws it.
4. A stationary cup on a table that stays in place until someone picks it up or knocks it over.
