Key Concepts

weight

Weight is the force exerted on a body due to gravity. It is defined as the product of an object’s mass and the gravitational acceleration experienced, thus making it dependent on the local gravitational field. For example, the weight of an object on Earth is greater than its weight on the Moon, even though its mass remains constant.

potential energy

Potential energy is the stored energy held by an object because of its position relative to other objects, internal stresses, or state. It often refers to gravitational potential energy, which depends on the height of an object in a gravitational field, but it can also include other forms like elastic potential energy. For instance, a ball held at a height possesses gravitational potential energy that converts to kinetic energy when dropped.

kinetic energy

Kinetic energy is the energy an object possesses due to its motion. It is directly proportional to the mass of the moving object and to the square of its velocity, indicating that even a small increase in speed results in a significant increase in kinetic energy. An example of kinetic energy is a moving car, where the speed and mass of the car determine its kinetic energy.

endothermic process

An endothermic process is a chemical or physical change that absorbs energy from the surroundings, typically in the form of heat. This energy absorption results in a decrease in temperature of the environment unless heat is supplied, making such processes useful in applications where cooling is desired. Dissolving certain salts in water, which leads to a temperature drop, is a common example of an endothermic process.

extensive property

An extensive property is a physical property of a system that depends on the amount or size of the material in the system. These properties, such as mass, volume, and energy, scale with the size of the system, meaning that doubling the system typically doubles the extensive properties. For instance, the total mass of two halves of a substance combined is equal to the sum of the masses of the individual halves.
