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...

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...

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 sm...
