Scalar, Vector, Distance, Displacement

Michael walks in the following order: from Point A, to Point B, and finally to Point C. Which is true?

• Distance and displacement are EQUAL

• Distance is less than displacement

• Displacement is less than distance.

Given the vector v = 3i -2j +6 k, the magnitude of a is:

• 36

• 49

• 7

• 6

The scalar product of u and v is zero, therefore...

• vectors u and v are parallel

• vectors u and v are perpendicular

• vectors u and v are equal

• vectors u and v are multiples

Find the dot product of <1, -2> and <3, 2>.

• 1

• <3, -4>

• <4, 0>

• -1

Vector is a quantity with:

• magnitude and direction

• magnitude

• direction

• none of the above

A quantity that needs both magnitude and direction to be fully described.

• Vector

• Scalar
