Dec 19, 2021 · What is Law of Inertia? The law of inertia is Newton’s first law, which states that “An object at rest will stay at rest, and an object in motion will stay in motion unless acted on by a net external force”.

Inertia is defined as the force which keeps stationary objects to stay still (remain at rest) or moving objects in motion at the same speed and in the same direction unless it is stopped by an external force. It can also be defined as the resistance of an object to resist change by remaining in its state of rest or in motion.
The concept of inertia lies in Newton’s first law of motion, which is also termed as the “Law of Inertia.” According to this law- Let’s look at an example to understand the concept of inertia in a better way. Let’s say a person is pedaling a bike and suddenly hits the front brakes. In this case, his/her body continues to move, and they fly over the...
(i). Satellites
A satellite is an object in space that circles or moves around a larger object. Do you know how it keeps moving around the bigger object without getting stopped? It’s due to the inertia of motion, which keeps it moving in a circular motion.
(ii). Falling of fruits and leaves
Have you ever wondered why the fruits or leaves fall down when the branches of a tree are shaken? It’s due to the inertia of rest. Before shaking, the branch is at rest, but when the tree is shaken, the branch starts moving, whereas the fruits and the leaves remain in their initial state of rest. Thus, they fall down.
(iii). Dusting a carpet
Do you know what makes the dust particles fall off the carpet? It’s all due to the magic of inertia. When you beat the carpet with a stick, the carpet starts moving but the dust particles in it remain in their initial state of inertia of rest. The repeated beating of the carpet causes the dust particles to drop, thus, giving you a clean carpet.
What Is the Law of Inertia? Law of inertia, also known as Newton’s first law of motion, states that An object will continue to be in the state of rest or in a state of motion unless an external force acts on it.

- The tendency of moving back when the stationary bus starts to move. Moving forward when a sudden brake is applied.
Law of inertia, postulate in physics that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force. This law is also the first of Isaac Newton’s three laws of motion.

4 days ago · Newton’s first law of motion is the law of inertia where an object at rest will remain at rest unless an object or an entity with an imbalanced force will act on it. The same is true for objects in motion.
Inertia is the tendency for an object at rest to remain at rest, or for a moving object to remain in motion in a straight line with constant speed. This key property of objects was first described by Galileo.
Sep 14, 2024 · This postulate is known as the law of inertia. The law of inertia was first formulated by Galileo Galilei for horizontal motion on Earth and was later generalized by René Descartes. Although the principle of inertia is the starting point and the fundamental assumption of classical mechanics, it is less than intuitively obvious to the untrained ...
