We are explaining the interaction between bodies. In this brief article, you'll discover all you need to know about contact force (s), types of contact force with examples, non-contact force (s), and examples. Let's start discussing one by one. Must Read: What is Force with Examples? Contact Force (s) The forces which act on bodies when they are in physical contact. These forces are produced and experienced when a body comes in contact with another body. For example, The force of friction (frictional force) Normal reaction force Force of tension exerted by a string Force exerted by a spring Force exerted on two bodies during collision  etc . When you pushed on an object you are definitely contacting the object directly or indirectly. Types of Contact Forces Frictional Force: When a body slide (or rolls) over a rough surface, a force starts acting on the body in a direction opposite to the motion of the body, along with the surface in contact. This is called the...

At the end of the article, you will be able to describe- What is Newtons Second Law -Definition, measurement of the 2nd law of motion, examples of newtons 2nd law. Let's start discussing one by one. Newtons 2nd Law of Motion This fact was first recognized by Newton who expressed it as his second law of motion. A Clue to the second law of motion - Suppose a fixed force is applied on the two bodies of different masses for the same duration. The lighter body gains a higher speed than the heavier one. However, the change in momentum in both cases is found to be the same. This shows that the same force for the same time causes the same change in momentum for bodies of different masses. Must Read: What is Momentum in simple terms? Just now I introduced momentum right. Why did I introduce momentum? it is because momentum played a role in Newton's second law of motion. In second law of motion, Newton basically told that there exists a relationship between force and moving them right....

By the end of this article, you should be able to define Wh at is linear momentum, definition, formula,  units, equation, describe the movement of objects. Let's discuss one by one. What is Momentum- Definition (Linear Momentum) It is the quantity of motion contained in the body.  Here's the key fact, All moving objects have momentum. But if an object is not moving its momentum is zero. Motion in a body can be produced or destroyed by applying force on it. Momentum is denoted by letter "p" Q -  A car has a mass of 1000 kilograms and it is not moving. What is a momentum (p) of the car?  Answer - In this case, the car's not moving and remember the objects that are not moving have a momentum of zero. The force required to start or stop a moving body depends upon. Mass of the Body -   When a ball and a big piece of stone are allowed to fall from the same height, we find that a much greater force is required to stop the big piece of stone than the ball. Thus la...

By the end of this article, you should be able to describe what is Newton's third law of motion- Definition, Formula, Equation, action-reaction pair forces and Examples of newtons 3rd law. Let's start discussing one by one. Newton's laws of motion. Sir Isaac Newton (1642-1727) made a systematic study of motion and extended the ideas of Galileo. He arrived at three laws of motion which are called Newton's laws of motion. What is Newtons Third Law - Definition According to Newton's 3rd law of motion, To every action, there is an equal and opposite reaction. Let us explain an activity to understand the law. Take a balloon and tie its mouth to a small piece of plastic tube with a narrow bore. Now inflate the balloon and close the opening of the tube with your finger. Remove the finger and let the air escape. The balloon will move in a direction opposite to the direction in which the air escapes. If we fix the inflated balloon on the top of a toy car. We observe that the...

Many a times question arises that what is Newton's first law of motion- Definition, Examples and what is its formula.  Our Today discussion about the newtons first law of motion. Let's start. Newton's laws of motion. Sir Isaac Newton (1642-1727) made a systematic study of motion and extended the ideas of Galileo. He arrived at three laws of motion which are called Newton's laws of motion.  What is Newtons First Law of Motion? This law consists of three parts: First part says that a body at rest continues in its state of rest. An external force has to be applied on it to make it move. A chair lying on the floor will continue to remain there unless we displace it. Second part says that a body in motion continues moving in a straight path with a uniform speed. This part seems to be contrary to our everyday experience. A rolling ball comes to rest on a rough ground. This is because of the force of friction. The ball moves through a larger distance on a smooth floor...

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 ...
