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…
Relative velocity refers to the velocity of an object with respect to another object. It is the difference between the velocity of the first object and the velocity of the second object, both measured with respect to the same frame of reference. For example, if a car is moving with a velocity of 60 km/h…
Uniform circular motion refers to the motion of an object moving in a circular path at a constant speed. In uniform circular motion, the object moves in a circle with a constant radius and a constant angular velocity. This means that the object travels the same distance along the circumference of the circle in equal…
