Basically, anything that can be measured (or calculated on the basis of other measurements) in the world around us. All sorts of measurements can be made, for example you can measure or calculate an object's length, width, mass, weight, density, you can measure an electric current, a voltage, etc. - all of these are physical quantities.
What else can I help you with?
Do motion has a direction?
One Direction ==================== Your question is irrelevant as it describes a state of a substance. It is merely the term for a body's relative change in position with respect to its surroundings. Only physical quantities can have direction. Physical quantities being only the vector quantities.
What are base quantities and derived quantities?
Base quantities are fundamental physical quantities that cannot be defined in terms of other physical quantities. They are used as building blocks in expressing other physical quantities. Derived quantities, on the other hand, are physical quantities that are derived from combinations of base quantities through multiplication and division with or without other derived quantities.
What are basic quantities and derived quantities?
Basic quantities are physical quantities that are independent and cannot be defined in terms of other physical quantities, such as length, time, and mass. Derived quantities, on the other hand, are physical quantities that are defined in terms of one or more basic quantities, such as speed, acceleration, and force.
Types of physical quantities?
Physical quantities can be broadly categorized as scalar or vector quantities. Scalar quantities have only magnitude, like mass or temperature, while vector quantities have both magnitude and direction, like velocity or force. Other types of physical quantities include derived quantities (obtained from combinations of base quantities) and dimensionless quantities (without units).
What physical quantities are being studied in kinematics?
In kinematics, physical quantities such as displacement, velocity, acceleration, and time are studied to describe and analyze the motion of objects without considering the forces causing the motion. These quantities help understand how objects move and change position over time.
What are theclassifications of physical quantities according to magnitude and direction?
Physical quantities that need both magnitude and direction for its complete description are known as vector quantities. Physical quantities that need only direction for its complete description are known as scalar quantities.
What term is defined as mathematical equations based on rules physics?
The term you are looking for is "physical equations." These equations describe the relationships between quantities in the physical world, often derived from fundamental principles of physics.
What do you understand by the term welfare of the child?
The physical need and the psychological need of the child are meat.
What refers to quantities such as area volume and velocity?
These quantities are referred to as physical quantities in the field of physics. They are measurable properties that can be described using mathematical values and units. Area and volume are examples of scalar physical quantities, while velocity is an example of a vector physical quantity.
What is a foundamental quantity?
A fundamental quantity is a physical quantity that is independent and not defined in terms of other physical quantities. These fundamental quantities form the basis for the measurement of other physical quantities. Examples of fundamental quantities include mass, length, time, and electric charge.
What is Differential of physics?
The term "differential of physics" typically refers to small changes or differentials in physical quantities, such as position, velocity, acceleration, or energy. Differential equations are used in physics to describe how these quantities change with respect to one another, and they are fundamental in understanding various physical phenomena.
What is definition of physical quantities?
Physical quantities are properties or attributes of phenomena that can be measured and expressed numerically. These quantities represent aspects of the physical world, such as length, mass, time, and temperature, and are typically described by a numerical value and a unit of measurement. Physical quantities form the basis of scientific measurement and analysis.
