Q
Given any two vectors, which statement is true?
-The magnitude of the sum of the two vectors is always smaller than either vector.
-The sum of the two vectors cannot be perpendicular to both vectors.
-The magnitude of the sum of the two vectors cannot be zero.
-The magnitude of the sum of the two vectors is always larger than either vector.
A
The sum of the two vectors cannot be perpendicular to both vectors.

Q
What is the area under a acceleration vs time graph?
A
Change in velocity
If the area is positive (above the time axis), then the velocity increases; if the area is negative (below the time axis), then the velocity decreases.
