The earthquake, which magnitude is higher than 7 on the Richter scale, is highly destructive. The power of an earthquake is expressed in terms of a magnitude and measured on a scale known as Richter scale (as shown in the image given below). The earthquakes mostly are caused by the movement of earth’s plates (as shown in the image below).Įarthquakes are also caused by volcanic eruption/activity, when a meteor hits the earth, or an underground nuclear explosion. The sound is something you can’t see, but hear or experience. The buzzing sound of an alarm clock helps you wake up in the morning as per your schedule. Physics gets involved in your daily life right after you wake up in the morning. The last major earthquake occurred in India on 8 th October 2005 in Uri and Tangdhar towns of North Kashmir and before that a major earthquake occurred on 26 th January 2001 in Bhuj, Gujarat. Let’s have ten examples of Physics in everyday life: 1. The major earthquakes are rare, but very much destructive. If a thunderstorm occurs there is also a possibility of lightning and cyclones.Īn earthquake is a sudden shaking or trembling of some region of the earth for a very short time.Īn earthquake is normally caused by a disturbance originated inside the earth’s crust.Įarthquakes keep occurring almost all the time, all over the earth, but most of them are not even noticeable. The metal columns used during the fixing of electrical wires and water pipes in the buildings also protect from the thunderstorm and lightning. The device, used to protect buildings from the effect of lightning, is known as Lightning Conductor.Ī metallic rod, taller than the building, is fixed in the walls of the building from top to toes during its construction protects from thunderstorm (as shown in the image given below). The process of electric discharge also occurs between two or more clouds, or between clouds and the earth (as shown in the image given below).ĭuring the lightning and the thunderstorm no open place is safe.Įlectrical appliances such as computers, TVs, etc., should be unplugged however, electrical lights can be left on, as they do not cause any harm. When negative and positive charges meet, it produces streaks of bright light and sound and the process is known as an electric discharge. The process of transferring of charge from a charged object to the earth is known as earthing. Some natural phenomena can cause large scale destruction of human life and property. When charges move, they constitute an electric current. When a plastic comb is rubbed with dry hair, it acquires some charge and the object is known as charged objects.
