Which pair includes a vector quantity and a scalar quantity respectively?
Correct answer: A. Force, kinetic energy
- A. Force, kinetic energy
- B. Velocity,acceleration
- C. Acceleration, displacement
- D. mass and momentum
Explanation
This is the correct answer. Force is a vector quantity because it has both magnitude (size) and direction. Kinetic energy is a scalar quantity because it has only magnitude and does not depend on direction

About Addition of Vectors
Vector addition combines directed quantities using the head-to-tail, parallelogram and component methods. Work includes finding the resultant magnitude and direction for two or more vectors, resolving vectors into perpendicular components, and distinguishing vector addition from scalar addition, where direction has no role.
