FORCE NEWTON LAWS OF MOTION

 Have you ever asked yourself why things go on?  Why do planets revolve around the sun?  Does spinning spin?  When we think that we have our own experience of moving from one place to another, it seems clear that we do not have to keep going or anything else.  Strikes for us like a machine.  To include, we can say that keep a thing on, it has to be pushed or pulled, this push or pull is called force.  There is no motion without force.  "Or is the root cause of motion. Thus, force gives an external effort (cause) in the form of a push or pull that either shifts or becomes the same to change the rest of the position. Of a straight line.  Along the motion of a body. Forces can be classified into two main categories; (1) Contact force: forces that come into play due to the actual contact between bodies under consideration. For example, friction force, tensile force  . A string, normal reaction, air resistance, etc. (i) Non-contact force: The forces that come into play without any physical contact between the bodies in question. These forces may be due to some intrinsic (inherent) property of the body.  For example, fields (electrical, magnetic and gravitational) are non-contact forces. 2. The concept of inertia has been discussed as the root cause of motion is a force. Now there are other questions that arouse suspicion.  Are, for example. Air molecules are constantly moving, what keeps them moving? Do things moving at different speeds require different forces? Are different things moving at the same speed?  Do things require equal force?  Why do we need a force to initiate motion or do we need a force to stop or change the direction of a moving object?  At this stage we can infer that this sequence of events is related to the intrinsic (inherent) property of a body called inertia.  We are believed in physicsby an external force is called inertia. Three types of inertia of the body  Is: inertia. Inertia of rest, motion, and inertia of direction. Inertia of rest: It is not the inability of the body to change itself in the event of inability. Example: The following examples show the inertia of the rest: (i)  When a bus, or a train, starts suddenly, a passenger standing inside bends backwards. This is because the passenger's feet, which are in contact with the floor of the bus, start moving,  But due to inertia, the upper part of the body is bent. To rest. Hence the passenger bends backwards. Similarly, a horse rider bends backwards when the horse starts running gallop. (When a  When the hanging carpet is beaten with a stick, the dust mites are cleaned. This is because, on beating, the carpet comes in motion but due to dust inertia, the wound remains and the wound remains  Falls under the inclination.  (ii) When a coin-carrying card and is quickly flipped with a finger placed on the bottle, the coin gets into a mess because it initially rests with both the card and the coin.  Upon flipping, the card is suddenly set in motion, while the coin remains due to inertia.  Therefore the card moves forward but the coin falls into the bottle.  (iv) When we shake a branch of the mango tree, the mango falls down.  When shaken, the branch comes into motion but, due to inertia, mangoes rest.  Therefore they separate and fall under gravity.  (150)
