Force-  Mechanics is the branch of physics that deals with the condition of rest or motion of material objects around us. It is one of the oldest branches of physics.The various sub-branches of mechanics in physics are: Static-Study of objects at rest or equilibrium. Kinematics- Deals with the motion of objects without considering the cause of motion. Dynamics- Deals with the motion of objects considering the cause of motion. Our Today discussion about - What Is Force- [Definition, Meaning, Examples] - Different Types of Forces And Their Examples. What Is Force - Definition A force is that physical cause which changes (or tends to change) either the size or shape  or the state of rest or motion of the body. -OR- It  is that cause (condition) which can produce the following two main effects: It can change the state of rest or motion of the body ( i.e., it can produce motion in the body). It can change the size or shape of the body.  ( i.e., it can change the dimensions of the body).

The term acceleration is a part of mechanics. Mechanics is the branch of physics that deals with the condition of rest or motion of material objects around us. It is one of the oldest branches of physics.The various sub-branches of mechanics in physics are: Static-Study of objects at rest or equilibrium. Kinematics- Deals with the motion of objects without considering the cause of motion. Dynamics- Deals with the motion of objects considering the cause of motion. Our Today discussion about the Kinematics. Lets start What Does Acceleration Mean? When moving object changes its velocity (speed in given direction), we use the term in Physics saying that body is accelerating. Object Changes Velocity =  Accelerating Question-  A car is travelling in a straight line at a constant velocity of 80 kilometres an hour. What is its acceleration? Answer- It is zero. It is because velocity is constant.There is no change in velocity. Question- A plane is travelling in a straight line at a cons

Any quantity that can be measured is a physical quantity. Physical quantities are classified as Vector quantity and Scalar quantity. What is Scalar Quantity? The physical quantities which require the only magnitude for their complete specification are called scalars or scalar quantity. They can be added up based on ordinary rules of algebra. Easy Understanding: If you are standing at a point A. One of your friend tells you that there is a treasure pot 50 kilometers away from home.  How long will you take to find it and in which direction will you go? It could be east, west, south or north. It is hard to know where exactly it is. You are only provided the Distance which is one-dimensional information. One dimensional information like 50 km is called a Scalar Quantity. Your Friend is just telling the distance not the direction. What is Vector Quantity? A quantity which has both magnitude and direction such quantities are referred to as vectors. Easy Understanding:  When you ask your

Law of Inertia Science: Remember physics is all about how things move and why things move. It was Sir Isaac Newton who discovered the three laws of motion. He was a scientist who lived from 1642 to 1727. Law of Inertia Definition Let's first learn about the first law of motion. It is also called the law of inertia. It states objects will remain at rest or in uniform motion in a straight line unless acted upon by an external unbalanced force. To understand Newton's first law completely. We need to learn about inertia first. What Does Inertia Mean? See a very large sofa what's special about it. It's stable it is not moving. Now go ahead and try to move it. The sofa itself is not willing to move. You can't move it. As it is very large. It means you had to put a huge effort. Now try to move a small stone. You can move it a little bit easier.  It means you had to put a small effort. It was also like it didn't want to move from its original position. Even the smaller

What is Eddy Current? The word Eddie literally means a circular current.  let us now try to understand how they are produced. Take a solenoid that has a soft iron core. Now connect this solenoid to an AC source. When a metallic disc is held over the cross-sectional face of the soft iron core the metallic disc will be thrown into the air. How does this happen? Current flows through the solenoid. Hence, magnetic flux linked with the solenoid increases from zero to finite value.  This change in magnetic flux gives rise to induced currents in the disk. The upper phase of the soft iron core attains the same polarity as the lower phase of the disk. Hence the disk is repelled by the soft iron core and is thrown up in the air. This experiment shows that when a conductor is kept in a changing magnetic field currents are induced in the body of the conductor. These are currents that occur in very small loops and are called eddy currents.  Foucault discovered this concept in 1895. In some cases,

The satellites classified into two types man-made (artificial satellite) and natural satellite. Here our main objective to discuss the artificial satellite, types, and how are satellite launch. What is Artificial Satellite? An artificial satellite is a man-made object orbiting around the earth. Artificial satellites are of two types namely:   geostationary satellites and  polar satellites let us now learn about the launching of artificial satellites and different types of satellites in detail. Geostationary Satellites Geostationary satellites are those satellites whose period of revolution around the earth is equal to the period of rotation of the earth. These satellites appear to be stationary as they revolve around the earth from west to east.  The period of revolution of the satellite is equal to the period of rotation of the earth. They revolve in the equatorial plane the orbits followed by geostationary satellites are called geostationary orbits or parking orbits. The height of

From the slums of Los Angeles to the beautiful skies of Whittier.  To the forgettable fog that travels through golden gate bridge of San Francisco. From route 66 to rocky skyline of the Utah mountains.  The Vandoleros Van Club have gone a trip.  Forever gone.  Creatively escaped this world before anyone could stop it.  Challenging authority and all of those who aren�t on the level.  making a bed on the road and making a bed into our work.  Our passion our brotherhood, our work, our lives, our club.  Within the thickness of our love comes support and within that support comes our work!  As a certified nut and Vandolero Van club member i�m extremely thrilled to be able to post along side of my brothers.  enjoy my work and you decide to purchase any of it you can reach me at  http://thestabbincabinvanco.bigcartel.com
