## Thermodynamic state function

Article with problems and solutions about thermodynamic state function In thermodynamics, state functions describe the equilibrium state of a thermodynamic system. They are independent of the path taken to reach a particular state and depend solely on the current state of the system. 1. Definition A thermodynamic state function, or simply a state function, is … Read more

## Thermal expansion coefficient units

Article with problems and solutions about thermal expansion coefficient units Thermal expansion is a material’s tendency to change in volume in response to a change in temperature. The coefficient of thermal expansion (CTE) quantifies this behavior and is an important parameter to consider in various engineering applications, ranging from bridge construction to electronic device fabrication. … Read more

## State newton’s first law of motion

Article with problems and solutions about state newton’s first law of motion Sir Isaac Newton’s First Law of Motion, commonly referred to as the Law of Inertia, lays the foundation for classical mechanics. It was first stated in Newton’s work “Mathematical Principles of Natural Philosophy,” published in 1687. The law describes the behavior of objects … Read more

## Practice problems density

Article with problems and solutions about Practice problems density Density is a physical property of matter that describes how much mass is contained in a given volume. It is mathematically expressed as: $\text{{Density}} = \frac{{\text{{mass}}}}{{\text{{volume}}}}$ where mass is measured in kilograms (kg), and volume is measured in cubic meters (m$$^3$$). Density is typically … Read more

Definition of Kinetic Energy Kinetic … Read more

## Non conservative forces examples

Article with problems and solutions about Non conservative forces examples Non-conservative forces are a critical concept in physics, especially in the field of classical mechanics. Unlike conservative forces, non-conservative forces depend on the path taken by an object, not just its initial and final positions. This leads to a loss or gain of mechanical energy … Read more

## Newton’s second law of motion definition

Article with problems and solutions about Newton’s second law of motion definition Newton’s Second Law of Motion is one of the three fundamental laws formulated by Sir Isaac Newton, providing a comprehensive description of the relationship between an object’s mass, its acceleration, and the force acting upon it. This law plays a crucial role in … Read more

## Kepler’s first law of planetary motion

Article with problems and solutions about Kepler’s first law of planetary motion Kepler’s first law of planetary motion is one of the three laws proposed by the German mathematician and astronomer Johannes Kepler. These laws describe the motion of planets around the Sun and provide a fundamental understanding of celestial mechanics. The first law is … Read more

## How to find the magnitude of displacement

Article with problems and solutions about how to find the magnitude of displacement Displacement is a vector quantity that describes the change in position of an object. It takes into account both the distance an object has moved and the direction of that movement. To find the magnitude of displacement, one only needs to know … Read more
