While there are many more (somewhat more obscure) conservation laws throughout physics (like "Conservation of Lepton Number"), I believe the four you may be referring to are
Conservation of Matter
Conservation of Energy
Conservation of Charge
Conservation of Momentum
NOTE that Conservation of Matter is not a true law (it is broken in many nuclear reactions). The other three are laws.
What else can I help you with?
What are the two physical quantities that are not conserved?
Entropy and work (by non-conservative force ) are not conserved
What quantities are conserved when balancing a nuclear reaction?
In order for a nuclear reaction to be balanced, there are quantities that must be conserved. The quantities are the atomic numbers and mass numbers of the particles involved in the reaction.
What are the two quantities are always conserved in nuclear decay equation?
Energy and electrical charge are two quantities that are always conserved in nuclear decay equation.
What quantities are conserved in an inelastic collision?
In an inelastic collision, momentum is conserved. However, kinetic energy is not conserved as it is transferred to other forms such as heat, sound, or deformation energy.
When is angular momentum conserved in a physical system?
Angular momentum is conserved in a physical system when there are no external torques acting on the system.
Which physical quantity is conserved when a planet revolves around the sun?
moment of inertia is conserved.
What is conserved in physical changes?
Mass and energy
What is a conserved quantity?
A conserved quantity is a physical property of a system that remains constant over time, even as the system undergoes changes. Examples include energy, momentum, and angular momentum. The conservation of these quantities is a fundamental principle in physics and often allows us to make predictions about the behavior of a system.
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 are four kinds of relationships between physical quantities?
The relationship can be more than, equal to, less than or a ratio.
