Vector vs. Scalar Physics

What is the definition of a vector quantity?

• A vector quantity is a quantity that has both magnitude and direction.

• A vector quantity is a quantity that has only magnitude.

• A vector quantity is a quantity that has both speed and direction.

• A vector quantity is a quantity that has only direction.

What is the definition of a scalar quantity?

• A scalar quantity is a physical quantity that has neither magnitude nor direction.

• A scalar quantity is a physical quantity that has direction only, without magnitude.

• A scalar quantity is a physical quantity that has both magnitude and direction.

• A scalar quantity is a physical quantity that has magnitude only, without any direction.

In graphical vector addition, how are vectors represented?

• As arrows with a specific length and direction

• As circles with varying radii

• As squares with different colors

• As text labels with different fonts

How is the resultant vector found in graphical vector addition?

• Divide the components of the vectors

• Multiply the magnitudes of the vectors

• Connect the tail of the first vector to the head of the second vector.

• Subtract the angles of the vectors

What is the process of analytically adding vectors?

• Subtract vectors from each other

• Break vectors into components, add corresponding components, combine results

• Multiply vectors by scalar values

• Divide vectors by scalar values

What are the components of a vector?

• Speed and time

• Height and weight

• Magnitude and direction

• Length and width

How can you find the x-component of a vector?

• Add the angle it makes with the x-axis to the magnitude of the vector

• Subtract the z-component from the magnitude of the vector

• Calculate the magnitude of the vector and multiply it by the cosine of the angle it makes with the x-axis.

• Divide the y-component by the magnitude of the vector

How can you find the y-component of a vector?

• y = magnitude + sin(theta)

• y = magnitude * sin(theta)

• y = magnitude * cos(theta)

• y = magnitude / sin(theta)

What is the magnitude of a vector?

• Magnitude of a vector is the length or size of the vector.

• Magnitude of a vector is the area enclosed by the vector.

• Magnitude of a vector is the direction of the vector.

• Magnitude of a vector is the speed of the vector.

What is the direction of a vector?

• From the initial point to the terminal point

• From the terminal point to the initial point

• In a circular motion

• In a zigzag pattern
