Direct relationships and inverse relationships. In direct relationships, two physical quantities change in the same direction (e.g., as one increases, the other also increases). In inverse relationships, two physical quantities change in opposite directions (e.g., as one increases, the other decreases).
Fundamental quantities are independent of other physical quantities, while derived quantities are based on combinations of fundamental quantities using mathematical operations. Derived quantities cannot exist without fundamental quantities as they rely on them for their definition and calculation.
The physical phenomena must be observable and measurable.
A physical state in which a substance can exist depends on its temperature and pressure. Common states include solid, liquid, gas, and plasma. For example, water can exist as ice (solid), liquid water, or steam (gas) depending on its temperature and pressure.
The study of the relationships between forces and the motion of objects is called mechanics. It involves analyzing how forces influence the velocity, acceleration, and position of objects. Mechanics can be further divided into classical mechanics, which deals with macroscopic objects, and quantum mechanics, which deals with microscopic particles.
No, a rock does not require energy to exist. Once formed, a rock can exist without needing external energy inputs to maintain its physical state.
Fundamental quantities are independent of other physical quantities, while derived quantities are based on combinations of fundamental quantities using mathematical operations. Derived quantities cannot exist without fundamental quantities as they rely on them for their definition and calculation.
Math is considered abstract because it deals with concepts and relationships that are not physical or tangible, but rather exist in the realm of ideas and logic.
The freezing point of mendelevium is not well-known since it is a radioactive element with a very short half-life and does not exist in nature in sufficient quantities to study its physical properties in detail.
Bohrium is a synthetic element that is highly radioactive and only produced in minute amounts. Due to its unstable nature, it does not exist in large enough quantities to exhibit any observable physical properties such as texture.
Directly proportional
Anywhere where negative quantities exist.

Scalar quantities are measurements which have no specific physical direction. Two fundamental scalar quantities are mass and time. Mass and time simply exist without any directionality whatsoever. By way of comparison, distance is a fundamental vector quantity and not a scalar quantity. You cannot travel any distance without going in a specific physical direction: up or down, left or right, north or south, forward or backward, etc.
A graph is one of the ways of showing the relationship that exist between two or more quantities.
