Question

which of the following quantities are vectors? (check all that apply)
speed
velocity
time
length
temperature
acceleration
volume
force
weight
area
displacement
mass
height

Explanation:

To determine which quantities are vectors, we recall that a vector quantity has both magnitude and direction, while a scalar quantity has only magnitude.

• Speed: Scalar (magnitude only, no direction).
• Velocity: Vector (magnitude and direction, e.g., 5 m/s east).
• Time: Scalar (magnitude only).
• Length: Scalar (magnitude only).
• Temperature: Scalar (magnitude only).
• Acceleration: Vector (magnitude and direction, e.g., 3 m/s² north).
• Volume: Scalar (magnitude only).
• Force: Vector (magnitude and direction, e.g., 10 N upward).
• Weight: Vector (it is a force due to gravity, so has magnitude and direction).
• Area: Scalar (magnitude only).
• Displacement: Vector (magnitude and direction, e.g., 10 m to the left).
• Mass: Scalar (magnitude only).
• Height: Scalar (magnitude only).

Answer:

Velocity, Acceleration, Force, Weight, Displacement
