Which of the following list of physical quantities consists only of vectors?
Correct answer: D. Force, acceleration, velocity
- A. Time, temperature, velocity
- B. Force, volume, momentum
- C. Velocity, acceleration, mass
- D. Force, acceleration, velocity
Explanation
Force is a vector quantity. It has both magnitude and direction. The direction of the force is as important as its magnitude in describing its effect. Acceleration is a vector quantity. It indicates the rate of change of velocity and has both magnitude and direction. Acceleration may involve speeding up, slowing down, or changing direction. Velocity is a vector quantity. It is the rate of change of displacement and includes both magnitude (speed) and direction. In summary, force, acceleration, and velocity are all vector quantities.

About Vectors and Equilibrium
Vectors have magnitude and direction, unlike scalars, and are combined by head-to-tail or parallelogram methods. Work covers rectangular components, equilibrium when the resultant force is zero, the scalar product for work and projections, and the vector product for torque and cross-product direction using the right-hand rule.
