Hello all steemians and science lover. Now i want to share a simple exsperiment Cutting Potatoes With Paper This experiment aims to know the moment of inertia.

Theoretical basis

What is Inertia?

Inertia is actually not a force at all, but rather a property that all things have due to the fact that they have mass. The more mass something has the more inertia it has. You can think of inertia as a property that makes it hard to push something around.

Other definition
Inertia is the resistance of any physical object to any change in its state of motion. This includes changes to the object's speed, direction, or state of rest.

Inertia is also defined as the tendency of objects to keep moving in a straight line at a constant velocity. The principle of inertia is one of the fundamental principles in classical physics that are still used to describe the motion of objects and how they are affected by the applied forces on them.

Inertia comes from the Latin word, iners, meaning idle, sluggish. Inertia is one of the primary manifestations of mass, which is a quantitative property of physical systems. Isaac Newton defined inertia as his first law in his Philosophiæ Naturalis Principia Mathematica, which states:

The vis insita, or innate force of matter, is a power of resisting by which every body, as much as in it lies, endeavours to preserve its present state, whether it be of rest or of moving uniformly forward in a straight line.

Apparatus and Materials

Knife
Tissues
Paper
Potatoes

[Image credit : school made]

Procedure:

Cut the potatoes using a piece of paper.
Grasp the edges of the paper. Try to keep the paper tense.
Shake fast and hard into potatoes.
Observe what happened ?

Conclusion

Potatoes that can be cut with paper, this is due to the inertial force. When we move the paper. Paper is moved with constant speed and force. While the potatoes remain silent. Potatoes will try to stay still when the paper touches the potatoes, and the paper itself will try to keep moving. As a result the paper can cut through the potatoes.
