Question 1
Scalars and VectorsWhich of the following is a set of vectors?
- A.Force, mass and moment
- B.Acceleration, velocity and moment
- C.Mass, weight and density
- D.Mass, volume and density.
Show the answer and explanation
Answer: B (Acceleration, velocity and moment)
Explanation
Acceleration, velocity and moment (torque) all have direction. Mass, volume and density are scalars, so every other set contains a scalar.
