Definition of Wave Reflection Reflection Defined: Wave reflection occurs when a wave hits a boundary and bounces back into the original medium. Reflection Defined: Wave reflection happens when a wave travels through a material and then hits a surface, like a wall or a mirror. Instead of going through that surface, the wave turns around … Read more

Damping Definition of Damping: Damping is the gradual loss of wave amplitude over time due to energy dissipation into the surroundings. Definition of Damping: Damping is a process where the back-and-forth movement of something, like a swing or a vibrating object, slowly becomes smaller and smaller over time. This happens because the object is losing … Read more

Definition of a Wave Origin of Waves: A wave is generated by a vibration or oscillation. Origin of Waves: A wave is created when something vibrates or moves back and forth very quickly. This vibration sends energy through the surrounding space or material. For example, when you pluck the string of a guitar, the string … Read more

Kinetic Theory of Gases Constant, Random Motion: Gas molecules are in continuous, random motion, colliding with each other and the container walls. Constant, Random Motion: Gas molecules are always moving in every direction at high speeds. They travel in straight lines until they bump into other gas molecules or hit the walls of the container. … Read more

Definition and Concept What Is Specific Latent Heat? It is the amount of thermal energy needed to change the state of 1 kg of a substance without altering its temperature. What Is Specific Latent Heat?: Specific latent heat is the amount of heat energy needed to change the state of 1 kilogram of a substance, … Read more

Definition and Formula What It Is: Specific heat capacity is the amount of heat required to raise the temperature of 1 kg of a substance by 1°C or 1 K. What It Is: Specific heat capacity is a property of matter that tells us how much heat energy is needed to increase the temperature of … Read more

Definition and Heat Transfer What Is Thermal Equilibrium? It is the state where two or more objects in contact reach the same temperature, stopping any net heat flow between them. What Is Thermal Equilibrium?: Thermal equilibrium is a condition where two or more objects that are touching or sharing a thermal connection end up having … Read more

Definition and Launch What Are They? Man-made satellites are artificial objects launched into space to orbit Earth or other celestial bodies for tasks like communication or data collection. What Are They?: Man-made satellites are artificial objects created by people and launched into space. They are designed to orbit the Earth or other celestial bodies, like … Read more

Discovery Kepler’s Contribution: Johannes Kepler discovered three laws that describe the motion of celestial bodies, especially planets around the Sun. Kepler’s Contribution: Johannes Kepler was a German astronomer who studied how planets move in space. After many years of observation and calculations, he discovered three important rules, now known as Kepler’s Laws. These laws explain … Read more

Gravitational Force Between Two Bodies Universal Attraction: Every object in the universe exerts a gravitational force on every other object. Universal Attraction: Every single object, no matter how big or small, pulls on every other object in the universe through a force called gravity. This force is always there, and it acts across even very … Read more
