What sign is this? X
Displacements
It is quantity by which just add them and minus them
Scalar Quantity
It is a quantity by which when calculating you have to consider the directions; manipulate the directions
Vector Quantity
The magnitude and the directions of the two velocities produce a vector sum that must be determined by a process called…
Vector Addition
———–>
Arrow-tipped line segment
In vector quantity, if a magnitude of given direction is (-), what does it mean?
Adjust the directions like to South. Change it from Vy -> V( half arrowed)
The vector sum of any two vectors can be found…..
Graphically
Rule of solving vector Addition depends on Tail and heads
Tail to head ( tail ) to Head
Rule in solving vector Addition in terms of putting the angle
Starting point of first vector to the resultant
In solving vector Addition, the same sum would result since
Vector a + vector b = vector b + vector a
When two quantities act in the same/opposite directions. Their numerical sum is the same as their algebraic sum.
Colinear vectors
——>—–>
Colinear vectors
Force which acts on the same point at the same time are called….
Concurrent forces
Direction of the vector is expressed in terms of angle in degrees,n alwayseasured from the….or…..
0 line or positive x-axis to the vector arrow
mks means
Meter, kilogram system, seconds
The unit of force is….
N newton
Aside from graphical method, what are other ways to solve for vector Addition
Analytical and Component ( polygon method )
In vector Addition of forces, does the rules of significant figures will not followed?
Yes
