Question

select all that apply
which of the following quantities are vectors?
speed
time
acceleration
change in velocity (δv)
change in time (δt)
velocity

Explanation:

Vectors are quantities that have both magnitude and direction, while scalars only have magnitude.

• Speed: Scalar (only magnitude)
• Time: Scalar (only magnitude)
• Acceleration: Vector (has magnitude and direction, as it is rate of velocity change)
• Change in velocity ($\Delta \mathbf{v}$): Vector (velocity is a vector, so its change has magnitude and direction)
• Change in time ($\Delta t$): Scalar (only magnitude)
• Velocity: Vector (has magnitude and direction)

Answer:

• Acceleration
• Change in velocity ($\Delta \mathbf{v}$)
• Velocity
