If two unit vector in same direction (along),third unit vector in opposite direction situated after applying law's of vector addition along coordinate we will gate unit vector..which is result of three unit vector.NOw in second case if two unit vector is 120 degree to each other the results will be equal...

Displacement, velocity, momentum, force are vector quantities

Jesee Bhatacharjii, God of Physics and Math. Just kidding. I'm really good at those two though.

Think of planar vectors. Say you add 3 unit vectors, each of which is perpendicular to the previous one, the resultant vector would be a unit vector. I'm talking about a system where the resultant would be the fourth side in a square. The remaining three sides would each be a unit vector Makes sense?...

Yes we can add and answer will not be changed even if two vectors are along the axis.

Current researcher in Gravity, wants to teach about the frontiers of physics

Just consider an unit square ABCD, where the vectors are AB,BC,CD (the direction is from the previous letter to latter); then the resultant,AD, will be another unit Vector. it doesnot change the fact, if 2 of them are along coordinate axes. Just draw a phasor diagram.Now, to be precise, this answer assumed...

If force is acting on a moving body perpendicular to the direction of motion, then what will be its effect on the speed and direction of the body?
The magnitude of velocity shall decrease and direction shall be same till it comes to rest, afterwards it shall move in direction of force with acceleration due to the applied force.

According to principle of conservation of energy, the total momentum of a system of masses in any direction remains constant unless acted upon by an external force in that direction. A. True B. False
This is not principle of conservation of energy but it is principle of conservation of momentum.

Sameer went on his bike from Delhi to Gurgaon at a speed of 60km/hr and came back at a speed of 40km/hr. What is his average speed for entire journey?
To find the average speed, you need to know the formula of average speed. The avg speed 0= 2 d / (t1+ t2) = 2 v1.v2/(V1 + V2). Just substitute the value.
