1) state the characteristics of a scalar quantity and give two examples of scalar quantities?
2)state the characteristics of a vector quantity and give two examples of vector quantities?

Hi


Scalars:
Some physical quantities can be described just by their numerical value (with their respective units) without directions (they don’t have any direction). The addition of these physical quantities follows the simple rules of algebra. Such physical quantities are known as scalars.

Example:
It is a scalar quantity and unit of mass is kg. If you are adding up two masses, let’s say: 5kg and 7kg, the total mass of the system will by (5 + 7) kg = 12kg
Other common examples of scalar quantities are: Temperature, Length, and Speed

Vectors:
Sometimes, to describe certain physical quantity, complete description of magnitude and direction is required (unlike scalars, they have a direction). The addition of these physical quantities does not follow the rules of algebra. To add vector quantities, special rules for the addition and subtraction of vectors are followed which we will learn as we go ahead in this chapter. These physical quantities are known as vectors.

Example:
Velocity is a vector quantity since it has both magnitude (numerical value) and direction. If you are saying that the velocity of a certain object is 5 m/s, it is incomplete since the direction of velocity is not mentioned. Velocity could be in any direction, so a certain direction has to be assigned to it in order to give complete information.
Other common examples of vector quantities are: Acceleration, Linear momentum and Force

You need to be more specific.  i really don't know what a "motion map" is.you can draw a graph of an object's position, distance, displacement, speed,velocity, or acceleration versus time, or you can draw a graph of the object's x-position versus its y-position and not give any information about time at all.if the graph presents position or displacement against time,  then constant velocity is a straight line . . i.e. a line that has  constant slope.if the graph shows speed against time, then constant velocityis a horizontal piece of line.if the graph shows acceleration against time, then constant  velocity is a piece of line that lies on the x-axis . . it's value is zero.
