Step-by-step explanation:

Answer 2

Answer:

Retardation: decreasing of velocity at a steady rate.

Velocity: speed in a stated direction

Vector quantities: quantities which have both magnitude and direction.

More information;

• Retardation is also the same as negative acceleration or deceleration.
• Speed is a scalar quantity since it only has a magnitude. Velocity is same as speed only difference is it includes direction;(speed in a given direction). Therefore, it becomes a vector quantity as vector quantities consists of both magnitude and direction.
• Magnitude; means the size.
