inertia

Today I have got you something interesting to explore. Today we are going to learn about inertia of motion. If a body is at rest in the first and then it starts moving all of a sudden the body tends to be in the state of rest for a bit more time this property is known as inertia or the inability of a body to change its state of rest or of uniform motion by itself is called inertia. Inertia of a body depends mainly upon its mass. If we kick a football, it flies away. But if we kick a stone of the same size with equal force, it hardly moves. Instead we may get injury our foot. A force, that is just enough to cause a small carriage to pick up a large velocity will produce a negligible change in the motion of the train. We say that the train has more inertia than the carriage. Clearly, more massive objects offer larger inertia. The inertia of an object is measured by its mass. The law of inertia is also known as the first law of motion. The first law of motion states that ‘An object remains in the state of rest or of uniform motion in a straight line unless compelled to change that state by a applied unbalanced force’. In other words,  All objects resist a change in their state of motion. The tendency of objects to stay at rest or to keep moving with the same velocity, unless it is acted by an external force.

I just typed this by squeezing my mind so if learned something from my typing please do comment something which you liked in this paragraph.
