Ready to inspect your relationship's foundation? Get "Build Before You Promise" → The Things We Learn Too Late The Warning Signs We Ignore Because We Want Love to Work Sometimes the hardest truth to accept is that wanting a relationship to succeed can make us overlook the very things we should be paying attention to. By Edwin Ogie • Author of Emotional Mastery , Build Before You Promise , and The Value of You This article draws from the core framework of Build Before You Promise —the critical work of reading the blueprint before you build, and learning to see warning signs before they become structural failures. If you have ever convinced yourself that love alone is enough to fix a cracked foundation, the issue may not be your heart. It may be that no one ever taught you how to inspect what you are building on. Read the Full Framework in...
In Physics and Mathematics, quantities are categorized into two major types: scalars and vectors.
Scalar Quantities
Scalar quantities have only magnitude (size) but no direction. They are represented by a single value. Examples include:
Distance
Speed
Mass
Temperature
Time
Vector Quantities
Vector quantities have both magnitude and direction. Examples include:
Displacement
Velocity
Force
Acceleration
Momentum
How to Find Vectors
1. Using Scale Drawing Method:
In this method, vectors are drawn to scale on paper. The steps include choosing a scale, drawing the vectors to scale, and measuring them. Use a ruler and protractor to measure the lengths and angles.
2. Using Analytical Method:
For any vector \( \vec{V} \) with magnitude \( V \) and direction \( \theta \), the components are calculated as:
Vx = V cos(ฮธ)
Vy = V sin(ฮธ)
Parallelogram Law of Vectors
The Parallelogram Law states that if two vectors \( \vec{A} \) and \( \vec{B} \) are represented by two adjacent sides of a parallelogram, then the diagonal represents the resultant vector.
The formula for the resultant vector \( R \) is:
R = √(A² + B² + 2AB cos(ฮธ))
Worked Example:
Given: \( A = 5 \, \text{N} \), \( B = 6 \, \text{N} \), \( \theta = 60^\circ \).
Find the resultant vector \( R \):
R = √(5² + 6² + 2 × 5 × 6 × cos(60°))
R = √(25 + 36 + 30) = √91 ≈ 9.53 N
Resolution of Vectors
Resolution of Vectors refers to breaking a vector into two perpendicular components, usually horizontal and vertical.
The components of a vector \( \vec{A} \) with magnitude \( A \) and angle \( ฮธ \) are:
1. Find the magnitude of the resultant vector if two vectors \( \vec{A} = 5 \, \text{N} \) and \( \vec{B} = 6 \, \text{N} \) make an angle of 60° with each other.
Answer:
R = √(A² + B² + 2AB cos(ฮธ))
R = √(5² + 6² + 2 × 5 × 6 × cos(60°)) = √91 ≈ 9.53 N
2. Resolve a vector of 12 N acting at 45° to the horizontal into its components.
FORGIVENESS THE SECRET TO A SUCCESSFUL RELATIONSHIP Forgiveness is a critical aspect of human relationships, particularly in marriage. Treating others with mercy and leniency requires you to overlook misunderstandings and the wrongs they have done to you. The capacity to forgive is a fundamental virtue that is the linchpin of safeguarding relationships and leading a flourishing life. Lack of forgiveness causes lots of damage to marriages, and it is often the root cause of divorce in our society. It is, therefore, vital to understand that forgiveness is the key to a lasting, successful, and fulfilling marriage. Before embarking on the journey of marriage, individuals should take responsibility and learn to know themselves deeply. It is essential to realize that marriage is not a walk in the park. It requires perseverance, tenacity, and a loving spirit from the partners involved. When hurt arises, forgiveness is an indispensable tool that partners must employ to calm their difference...
