Momentum

Momentum is a quantity that expresses the motion of a body, equal to the product of its mass and velocity. The momentum of an object depends on its mass and velocity, with greater mass or velocity resulting in more momentum. The law of conservation of momentum states that in a closed system without external forces, the total momentum before and after an interaction will be the same. Examples include a person recoiling after firing a gun or moving backward when throwing an object off a skateboard. In collisions, the total momentum of the system is conserved and can be expressed mathematically as the sum of the momentum of the objects before equalling the sum after.

Errors and uncertainties in physics

Every measurement has uncertainty that arises from limitations in measuring devices, techniques, and the inherent variability in what is being measured. There are several types of uncertainty: absolute uncertainty is the value given directly by the measurement; fractional and percent uncertainties relate the absolute uncertainty to the measured value. The proper method for determining the combined uncertainty when calculations are performed on measurements depends on whether values are added, subtracted, multiplied, divided, or raised to a power. Accounting accurately for uncertainty is crucial for scientific validity.

1_PHYSICAL Quantities to define the laws of physics

This document discusses physical quantities and units in the International System of Units (SI). It defines a physical quantity as a property that can be measured, such as length, time, or temperature. All physical quantities have a numerical value and a unit. Quantities are either base quantities, such as length, mass, and time, which are defined by the SI, or derived quantities, which are combinations of base quantities. The document lists the seven base quantities in SI and provides examples of derived quantities and their units. It also discusses using base units to check the homogeneity of equations and expresses derived units as products or quotions of base units.

2-1 Intro To Vectors

Vectors have both magnitude and direction, while scalars only have magnitude. Common vectors include displacement, velocity, and force. Vectors can be added and subtracted graphically by placing the tail of one vector at the head of another, with the resultant vector running from the tail of the first to the head of the last. Multiplying or dividing a vector by a scalar does not change its direction.

Mechanics

This document discusses measurement, physical quantities, dimensions, and dimensional analysis. It defines fundamental and derived physical quantities. Dimension is defined as how physical quantities relate to fundamental quantities of mass, length, and time. Dimensional analysis shows how physical quantities relate to each other and can be used to derive formulas, check the homogeneity of equations, and convert between units. Errors are deviations between measured and exact values. Dimensional analysis has limitations and cannot be used for trigonometric, logarithmic, or exponential formulas or detect dimensionless constants.

Vectors And Scalars And Kinematics

Vectors and scalars can be distinguished as either having magnitude and direction (vectors) or just magnitude (scalars). Examples of vectors include displacement, velocity, and force, while examples of scalars include length, time, and speed. Vectors can be added graphically by placing the tail of one arrow at the head of another, with the line between the free tail and head giving the resultant vector. Vectors can also be resolved into perpendicular components along chosen axes or subtracted by adding the opposite vector.

Presentation1.ppt

Computational fluid dynamics (CFD) uses numerical methods and algorithms to solve and analyze fluid flow problems. CFD allows for the analysis of systems with complex geometries and fluid behavior by discretizing the fluid domain and solving the governing equations. The goal of CFD is to replace differential conservation equations with algebraic approximations that can be solved using numerical techniques on a computational grid. CFD simulations require discretizing the flow field, discretizing equations of motion, and solving the resulting algebraic equations to determine variable values at grid nodes.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

- 4. Unit Conversion for Areas and Volumes Length 1 mm = 10-3m Areas Squaring both sides 1 mm2 = (10-3)2 m2 = 10-6 m2 Volume Cubing both sides 1 mm3 = (10-3)3 m3 = 10-9 m3
- 5. Base Units
- 6. Derived Units consists of some combination of the base units. The base units may be multiplied together or divided by one another, but never added or subtracted
- 8. In any equation where each term has the same base units, the equation is said to be homogeneous or ‘balanced’.
- 9. A quantity which can be described fully by giving its magnitudeis known as a scalar quantity. A vector quantity has magnitudeand direction.
- 10. Scalar and Vector Quantities
- 11. Vector Representation One way to represent a vector is by means of an arrow. The directionof the arrow is the directionof the vector quantity. The lengthof the arrow, drawn to scale, represents its magnitude.
- 12. Addition of Vectors The combined effect of two (or more) vectors is called the resultant. Coplanar (all in the same plane) vectors may be added (or subtracted) using a vector diagram. The resultant may be found using a scale drawing of the vector diagram of by calculation.
- 13. Resolution of Vectors A single vector may be divided into two separate components. The dividing of a vector into components is known as the resolution of the vector. In general, a vector is resolved into two components at right-angles to each other.
