KINEMATICS IN TWO OR THREE DIMENSIONS; VECTORS
VECTORS & SCALARS
Vector-magnitude & direction
Scalar-Magnitude only :
ADDITION OF VECTORS (GRAPHICAL METJHOD)
Two dimension
Tail-to-tip method
Pythagorean method
Parallelogram method
One dimension
Simple subtraction & addition
SUBTRACTION & MULTIPLICATION OF VECTOR BY A SCALAR
Subtraction - Define negative vector whuch has same magnitude but opposite direction
Multiplication - dot/cross product
ADDING VECTORS BY COMPONENTS
Two dimension
Use trogonometric functions
one dimension
Added arithmetically
VECTOR KINEMATICS
Instantaneous velocity : dr/dt
Instantaneous acceleration : dv/dt
PROJECTILE MOTION
Vertical motion
a=--g , at highest point v=0
Horizontal motion
a=o , v= constant
