Science > Physics > Newton’s Laws of Motion > Reference Frames Before studying Newton’s laws of motion, we shall understand a very important concept of reference frames in this article. Motion is a Relative Concept: Motion is always with respect to the observer. Consider a person A is standing in a train moving in the […]
Science > Physics > Force > Simple Numerical Problems on Force In this article, we shall study to solve numerical problems to calculate the magnitude of force, momentum, and change in momentum. Example – 01: The speed of a tortoise and hare are 1 m/s and 3 m/s respectively. The mass of the hare is 5 […]
Science > Physics > Force > Applications of Newton’s Laws Newton’s laws of motion have everyday applications. The change in momentum of a body in a small time is a cause of large force. Most of the applications are related to the concept of change in momentum. Cricket fielder lowers his hand while catching a […]
Science > Physics > Force > Newton’s Third Law of Motion In this article, we shall study Newton’s third law of motion and the concept of action-reaction pair of forces. Statement: To every action, there is always equal, opposite and simultaneous reaction. Explanation: Let us consider a block of metal kept on the table. The […]
Science > Physics > Force > Newton’s Second Law of Motion In this article, we should study the concept of momentum and Newton’s Second Law of Motion. To apply Newton’s second law of motion, the body should be acted upon by an unbalanced force. Thus to apply this law we should consider a net force […]
Science > Physics > Force > Newton’s First Law of Motion Newton’s laws of motion are three physical laws that, together, laid the foundation for classical mechanics. In this article, we shall discuss Newton’s first law of motion and the concept of inertia of a body. Statement of Newton’s First Law of Motion: Every material body […]
