Ans:
Displacement is a vector quantity because it has both magnitude and direction. When an object moves from one position to another, its displacement is the straight-line distance between the initial and final positions, along with the direction from the starting point to the ending point.
On the other hand, energy is a scalar quantity because it only has magnitude and no specific direction associated with it. For instance, the kinetic energy of an
object depends only on its speed and mass, not on the direction in which it is moving. Therefore, energy is classified as a scalar quantity.
