Relative position summary

The video tutorial explains how to determine the position vectors of two airplanes, A and B, using a fixed axis at a reference point. It introduces the concept of a moving Cartesian axis for pilot B to find the relative position vector of airplane A. The tutorial further demonstrates how vector addition can be used to relate these position vectors, showing that the position vector of A is equal to the sum of the position vector of B and the relative position vector of A with respect to B.

What is the purpose of drawing a fixed axis at a reference point when determining the position vectors of airplanes A and B?

• To calculate the fuel consumption of the airplanes

• To determine the altitude of the airplanes

• To establish a common reference for calculating position vectors

• To measure the speed of the airplanes

How does the pilot of airplane B find the position vector of airplane A relative to her position?

• By using a rotating axis

• By using a fixed axis at the reference point

• By creating a moving Cartesian axis

• By measuring the distance directly

What does the vector RAB represent in the context of the airplanes?

• The position of airplane A relative to airplane B

• The speed of airplane A

• The altitude of airplane B

• The position of airplane B relative to airplane A

Which equation represents the relationship between the position vectors RA, RB, and RAB?

• RA = RAB + RB

• RA = RB - RAB

• RA = RB + RAB

• RA = RAB - RB

What is the definition of the position vector RA?

• The position vector from O to A

• The position vector from B to A

• The position vector from A to B

• The position vector from O to B
