The center of mass (also known as the center of gravity) is a point in an object or a system of objects where the mass of the system is concentrated. It is the average position of all the parts of the system, weighted according to their respective masses. The center of mass is an important…
In classical mechanics, a system of particles refers to a collection of particles that interact with each other through various physical forces, such as gravitational, electromagnetic, and nuclear forces. The behavior of a system of particles can be analyzed using Newton’s laws of motion, which describe the motion of individual particles and the resultant motion…
Mechanical energy is the sum of kinetic energy and potential energy of an object due to its position, motion, or both. Kinetic energy is the energy an object possesses due to its motion, while potential energy is the energy an object possesses due to its position or state of being. The total mechanical energy of…
The conservation of linear momentum is a fundamental principle in physics that states that the total momentum of a system of interacting objects remains constant, unless acted upon by an external force. In other words, if two objects interact with each other, the total momentum of the system before and after the interaction must be…
Work and power are both concepts in physics that describe the transfer of energy from one object to another. Work is defined as the product of the force applied to an object and the displacement of the object in the direction of the force. In other words, work is done when a force acts on…
Kinetic energy and potential energy are two forms of energy that an object can possess. Kinetic energy is the energy that an object possesses due to its motion. The amount of kinetic energy an object has depends on its mass and velocity. The formula for kinetic energy is: KE = 1/2 mv^2 Where KE is…
Static friction and dynamic friction are two types of frictional forces that act on objects in contact with each other. Static friction is the force that prevents an object from moving when a force is applied to it. It is a type of frictional force that opposes motion between two objects in contact with each…
In physics, a frame of reference is a coordinate system used to describe the position and motion of objects in space. When an observer is in a state of constant motion with respect to another observer, they are said to be in different frames of reference. A uniformly accelerated frame of reference is a frame…
The term “inertial” is related to the concept of inertia, which is the tendency of an object to resist any change in its state of motion. Inertia is a property of matter that makes it difficult to accelerate or decelerate an object. An object in motion tends to stay in motion, and an object at…
Newton’s laws of motion are a set of three fundamental principles that describe the behavior of objects in motion, as formulated by the English physicist Sir Isaac Newton in the 17th century. They are as follows: These laws have been foundational in the development of classical mechanics and have been used to describe the motion…
