KINEMATICS IN TWO OR THREE DIMENSIONS;VECTORS
VECTORS AND SCALARS
vectors has magnitude & scalar
scalars has only magnitude
ADDITION OF VECTORS -GRAPHICAL METHODS
Tail-to-tip
Parellogram method
SUBTRACTION & MULTIPLICATION OF VECTORS BY SCALAR
Multiplication
Subtraction
ADDING VECTORS BY COMPONENTS
If components are perpendicular can use trigonometric functiovns
Components can be added arithmetically because they are one dimension
UNIT VECTORS
A vector with magnitude 1
VECTOR KINEMATICS
Motions in components.3 independent motions in each dimension
PROJECTILE MOTION
Horizontal
-Acceleration is zero
-Velocity=0m/s
Vertical
-Acceleration=9.80m/s
-At highest point,v=0m/s
RELATIVE VELOCITY
Velocity is known relative to a reference frame that is moving relative to earth
