Unit 3 Week 2

Front

What is a curl?

Back

A curl is a type of movement or shape that resembles a spiral or loop. In mathematics, it can refer to a specific operation in vector calculus that measures the rotation of a field.

Front

Define 'vector' in simple terms.

Back

A vector is a quantity that has both direction and magnitude. For example, if you think of an arrow, the length of the arrow shows how much (magnitude) and the way it points shows the direction.

Front

What does 'magnitude' mean?

Back

Magnitude refers to the size or amount of something. In math, it often describes how large a number is, regardless of its sign.

Front

Explain what 'direction' means in terms of vectors.

Back

Direction indicates where something is pointing or moving towards. In vectors, it shows the way the vector is heading.

Front

What is a 'field' in mathematics?

Back

A field is a set of numbers or functions that you can add, subtract, multiply, and divide. For example, the set of all real numbers is a field.

Front

What is the purpose of matching in a quiz?

Back

Matching helps to connect related concepts or terms, making it easier to understand how they are related.

Front

What does 'rotation' mean in geometry?

Back

Rotation is turning around a point. For example, if you spin a wheel, it rotates around its center.

Front

Define 'spiral'.

Back

A spiral is a curve that starts from a point and moves farther away as it winds around that point, like a spring or a snail shell.

Front

What is a 'loop'?

Back

A loop is a shape that curves back on itself, forming a closed path, like a circle or a ring.

Front

Explain the term 'operation' in mathematics.

Back

An operation is a mathematical process like addition, subtraction, multiplication, or division that you perform on numbers.
