PHYSICS 2 AND 1 COMBINED

is one that has nothing to do with spatial direction

SPATIAL DIRECCTION = LEFT, RIGHT, UP , DOWN

Scalar Quantity, or scalar

7 EXAMPLES OF SCALAR QUANTITY

● Length

● Time

● Temperature

● Mass

● Density

● Charge

● Volume

HAVE magnitude (size) and direction

Vector Quantity

5 EXAMPLES OF VECTOR QUANTITY

● Displacement

● Velocity

● Acceleration

● Force

● Momentum

or sum, of a number of vectors of a particular type (force vectors, for example) is that single vector that would have the same effect as all the original vectors taken together

RESULTANT FORCE

2 METHODS OF ADDING VECTORS

GRAPHICAL SOLUTION

ANALYTICAL SOLUTION

2 TYPES OF GRAPHICAL SOLUTION

PARALLELOGRAM METHOD

POLYGON METHOD

4 TYPES OF ANALYTICAL SOLUTION

a. Trigonometric Function

b. Pythagorean Theorem

c. Cosine Law, Sine Law

d. Component Method of Adding Vectors

For adding two vectors: The resultant of two vectors acting at any angle may be presented by the diagonal of a parallelogram

Parallelogram Method

This method for finding the resultant of several vectors consists in the beginning at any convenient point and drawing (to scale and in the proper directions) each vector arrow in turn. They may be taken in any order of succession. The tail end of each arrow is positioned at the tip end of the preceding one

Polygon Method

a single force that produces the same effect on an object as the combined effect of multiple forces acting on that object

RESULTANT FORCE

is equal in magnitude to the resultant force but acts in the opposite direction

EQUILIBRANT FORCE
