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

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
