Vector quantities have magnitude and direction

Steps:

• Recall that vector quantities possess both magnitude and direction, unlike scalars which have only magnitude.
• Examine option A: displacement has direction (vector), but distance does not (scalar).
• Examine option B: force (F = ma) and momentum (p = mv) both involve direction from acceleration and velocity.
• Examine options C and D: torque is vector, but time is scalar; weight is vector, but pressure (force per area) is scalar.

Why B is correct:

• Force and linear momentum are both vectors, as defined by Newton's second law (F = dp/dt) where direction matters for their effects.

Why the others are wrong:

• A: Distance is a scalar quantity measuring path length without direction.
• C: Time is a scalar quantity with only magnitude.
• D: Pressure is a scalar quantity, independent of direction.

Final answer: B
