Vectors

Front

What is a vector?

Back

A vector is a quantity that has both magnitude and direction, such as displacement, velocity, and force.

Front

What is the Tip to Tail method?

Back

The Tip to Tail method is a graphical way to add vectors by placing the tail of one vector at the tip of another.

Front

What is the magnitude of a vector?

Back

The magnitude of a vector is the length of the vector, representing its size or amount.

Front

How do you find the resultant vector?

Back

The resultant vector is found by adding two or more vectors together, either graphically using the Tip to Tail method or mathematically using vector addition formulas.

Front

What is the difference between scalar and vector quantities?

Back

Scalar quantities have only magnitude (e.g., temperature, mass), while vector quantities have both magnitude and direction (e.g., velocity, force).

Front

What is the formula for calculating the magnitude of a resultant vector from two perpendicular vectors?

Back

Front

What does the direction of a vector indicate?

Back

The direction of a vector indicates the path along which the vector acts, often represented by angles or compass directions.

Front

What is a resultant vector?

Back

A resultant vector is the single vector that has the same effect as two or more vectors acting together.

Front

How do you represent vectors graphically?

Back

Vectors are represented graphically as arrows, where the length of the arrow indicates the magnitude and the arrowhead indicates the direction.

Front

What is the significance of the angle between two vectors?

Back

The angle between two vectors affects the magnitude of the resultant vector when they are added; it is crucial for calculating the resultant using the cosine rule.
