What does it mean to say momentum is conserved?
What does it mean to say momentum is conserved?
What other physical quantities are quantized apart from charge?
Volume and mass or physical qualities related to weight and size of the actual specimen. Density, hardness, and molecular weight are physical qualities that are quantized based on the material.
If momentum were conserved the ratio of the total momentum after the collision to the total momentum before the collision would be?
1 +/- two decimal place
Are there different types of decibels?
Decibels (dB) mean a logarithmic unit of measurement that expresses the magnitude of a physical quantity relative to a specified or implied reference level. Since it expresses a ratio of two quantities with the same unit, it is a dimensionless unit. Decibel is Decibel!
What compares or shows the relationship of two quantities in science?
these type of quantities are called derived quantities. Their value depends on some fundamental quantities or some other derived quantities. eg. force is a derived quantity whose value depends on mass(fundamental) and acceleration(derived).
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 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 is the two types of physical quantities?
Generally there are two types of physical quantities. One without direction known as scalars other with direction known as vectors. While there are other physical quantities as well that cannot be classified under the two above mentioned categories, they are tensors, matrices, spinors and quaternions.
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 is the ratio of two different physical quantities?
Rate
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 are the two types of relationships that exist amongst physical quantities?
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).
What is the two groups of physical quantities?
Physical quantities can be broadly categorized into two groups: scalar quantities and vector quantities. Scalar quantities have only magnitude and include measurements like mass, temperature, and time. In contrast, vector quantities possess both magnitude and direction, such as velocity, force, and displacement. This distinction is essential in physics for accurately describing and analyzing different phenomena.
What requirements must be met by two physical quantities when they are added together?
When two physical quantities are added together, they must have the same units in order to be combined. This means that both quantities must be expressed in the same type of measurement, such as meters or kilograms, for the addition to be valid.
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.
