Energy is the capacity to do work or produce change. It exists in forms like kinetic, potential, thermal, chemical, and nuclear. Energy transforms but cannot be created or destroyed (law of conservation). It’s essential for life, powering everything from biological ...
Resultant refers to the combined effect of two or more vectors acting on an object. It is a single vector that represents the sum of all individual vectors. The direction and magnitude of the resultant depend on the direction and ...
Mass is a fundamental property of matter that measures the amount of substance in an object. It is a scalar quantity and remains constant regardless of location. Mass is typically measured in kilograms (kg) and determines an object’s resistance to ...
Temperature is a measure of the average kinetic energy of particles in a substance. It determines the direction of heat flow, with heat moving from higher to lower temperatures. Temperature is measured in Celsius, Kelvin, or Fahrenheit scales and plays ...
A thermometer is an instrument used to measure temperature. It operates on the principle that the physical properties of materials change with temperature. Common types include mercury thermometers, alcohol thermometers, and digital thermometers. They are used in various fields such ...
A thermometer is a device used to measure temperature. It operates on the principle of thermal expansion of liquids or changes in electrical resistance. Common types include mercury thermometers alcohol thermometers and digital thermometers. Thermometers are widely used in weather ...
The kinetic theory of matter explains that matter is made up of tiny particles in constant motion. These particles collide with each other and the walls of their container, resulting in pressure and temperature. The theory describes the relationship between ...
Wavelength is the distance between two consecutive peaks or troughs of a wave. It is commonly used to describe waves, including light, sound, and electromagnetic waves. Wavelength is inversely proportional to frequency, meaning shorter wavelengths correspond to higher frequencies. It ...
Wavelength is the distance between two consecutive crests or troughs of a wave. It is a fundamental property of waves, including light and sound, determining their energy and frequency. Wavelength is inversely proportional to frequency and is commonly measured in ...
