Answers
Answer:
Velocity: Velocity is a physical vector quantity. It has a magnitude as well as direction.
...
Speed & Velocity.
Speed Velocity
Speed is a scalar quantity Velocity is a vector quantity.
Speed ascertains how fast a body moves. Velocity ascertains the object's speed and the direction it takes while moving.
Examples of Vector Quantities. Vector quantities refer to both the direction of the medium's movement as well as the measurement of the scalar quantity. You may notice that you can find scalar products are often the products of two vector quantities.
Vector, in physics, a quantity that has both magnitude and direction. It is typically represented by an arrow whose direction is the same as that of the quantity and whose length is proportional to the quantity's magnitude. Although a vector has magnitude and direction, it does not have position.
1 Speed : Speed is defined as the distance traveled by an object with respect to the time taken. ... Velocity : Velocity is defined as the rate of change of position of an object with respect to the time. It is a vector quantity that means it tell us about the magnitude and direction of an object.
