in 6th grade in class 6c
come and find me i gave you all the information you basically needed to find me
and you can only come to my school on monday Tuesday Wednesday Thursday and f riday
some days i might be absent
or either you can call me school to find me
As the velocities are in the same direction then addition of vectors becomes so easy. We simply add the magnitudes of the velocities. If velocities go exactly opposite, then we get the difference of their magnitudes. If velocity vectors get inclined, then we use the parallelogram law of vectors to get the resultant.
Only if the two velocities are equal in magnitude but in opposite directions.
When you combine 2 velocities that are in the same directions, add them together to find the resultant velocity. When you combine 2 velocities that are in opposite directions, subtract the smaller velocity from the larger velocity to find the resultant velocity.
Because the two velocities are in the opposite directions, you can directly subtract their numeric values. (1400 - 20) kph in the larger velocities direction. The answer is 1380 kph West.

The zero-vector has no direction.
Thee direction of the two vectors.
a resultant vector not only the resultant of two or three vector. it is the resultant direction of two or many vectors.(let us push an object with same force in opposite direction the resultant is zero and if we push in same direction the force will double.if we pull a object with same force in x and y direction the resultant force in 45 degrees to x axis)
forces in the same direction can be added to give us the resultant force and opposite force will subtracted to get resultant force
Deceleration is merely acceleration in a direction opposite to the original motion. If something isnt moving it cannot be decelerated but if it is moving and the resultant force acts in the opposite direction to motion it will decelerate the object.
A couple: 2 parallel forces equal in magnitude, but opposite in direction separated by a distance.
