Card 1
Question: What is a scalar quantity?
Answer: A scalar quantity is one that can be fully described by a single numerical value, representing its size or amount, without an associated direction.
Card 2
Question: What are some examples of scalar quantities?
Answer: Examples of scalar quantities include temperature, mass, time, and speed.
Card 3
Question: What is a vector quantity?
Answer: A vector quantity is one that possesses both magnitude (size) and direction.
Card 4
Question: What are some examples of vector quantities?
Answer: Common examples of vector quantities include displacement, velocity, acceleration, and force.
Card 5
Question: How is a vector often represented geometrically?
Answer: A vector is often represented as a directed line segment or an arrow.
Card 6
Question: In a geometric representation of a vector, what does the length of the arrow represent?
Answer: The length of the arrow represents the vector's magnitude.
Card 7
Question: In a geometric representation of a vector, what does the arrowhead indicate?
Answer: The arrowhead indicates the vector's direction.
Card 8
Question: How can a vector be denoted symbolically?
Answer: A vector can be denoted by a boldface letter, such as **a**, or by an arrow above a letter, such as →a. If a vector starts at point A and ends at poin
Card 9
Question: What are the starting and ending points of a vector called?
Answer: The starting point of a vector is called its initial point or tail, and the ending point is called its terminal point or head.
Card 10
Question: How is a vector represented using components in a 2D Cartesian coordinate system?
Answer: In a 2D Cartesian coordinate system, a vector **v** can be represented by an ordered pair of numbers (v₁, v₂), where v₁ is the component along the x-a
