Understanding Vectors and Their Components

What is a vector in physics?

• A quantity with only magnitude

• A quantity with both magnitude and direction

• A quantity with only direction

• A quantity with neither magnitude nor direction

Which of the following is NOT a vector quantity?

• Displacement

• Velocity

• Speed

• Force

What is the purpose of vector addition in physics?

• To determine the magnitude of a single vector

• To find the resultant vector from two or more vectors

• To convert a vector into its components

• To calculate the direction of a vector

How can a vector directed at an angle be broken down?

• Into a single component

• Into two components aligned with the coordinate axes

• Into three components

• Into components that are not aligned with the coordinate axes

What method can be used to find a vector's magnitude from its components?

• Trigonometric methods

• Head-to-tail method

• Pythagorean theorem

• Vector subtraction
