Define
a. scalar,
b. vector,
c. velocity,
d. position,
e. distance,
f. hypothesis,
g. variable,
h. independent variable,
i. dependent variable,
j. scientific notation.

a. Scalar - A scalar quantity has only magnitude and does not have a direction.

b. Vector - A vector quantity has both direction and magnitude to determine the position of a point in space relative to another point.

c. Velocity - Velocity is defined as the speed of an object in a given direction.  

d. Position - Position is the space occupied by any object with respect to another object.

e. Distance - The distance between two points is defined as the length of a straight line segment that links them.

f. Hypothesis - It is defined as a proposed explanation that acts as a starting point for further investigation.

g. Variable - Variable is defined as something whose value changes in an equation or experiment.

h. Independent Variable - The variable that does not depend or change with other variables.

i. Dependent Variable -  The variable that depends on the working of other variable.

j. Scientific Notation - It is the way that is used to handle very large numbers or very small numbers. Like 0.0000000065, we write 6.5 x 10^-9.
