Vectors

Question 3 • [HSPHY] Physics Sem 1 (26-27)

Assuming motion is on a straight path, what would result in two positive components of a vector?

Answer
A
a train moving north of east at an angle of 25°
B
a bus moving north of east at an angle of 95°
C
a boat moving south of west at an angle of 40°
D
a car moving south of west at an angle of 10°

Explanation

A vector has two positive components when it points in the positive directions of both axes: east (positive x) and north (positive y). A train moving 25° north of east has both an eastward and a northward component, so both are positive. The other directions include a westward or southward component, or point mostly west or south.
