5 m/s North is an example of a(n) ________________

• Speed

• Velocity

• Position

• Acceleration

Which of the following is NOT a vector?

• Velocity

• Distance

• Acceleration

• Displacement

If you ride your bicycle down a straight road for 500 m and then turn around and ride back, your distance is _________ your displacement.

• greater than

• equal to

• less than

• unknown

If vector A is 5 m North, then vector -A would be:

• 5 m North

• -5 m North

• 5 m South

• -5 m East

A ball is kicked straight up into the air at 10 m/s.  If you wanted to find the maximum height, you would know the following terms:

• v0 = 0m/s;

  v = 10m/s;

  a = −9.8m/s^2

• v0 = 10m/s;

  v = 0m/s;

  a = −9.8m/s^2

• v0 = 0m/s;

  v = 10m/s;

  a = 0m/s^2

• v0 = 10m/s;

  v = 0m/s;

  a=0m/s^2

ALL vector quantities must include:

• magnitude and units

• direction only

• magnitude, units, and direction

• units and direction

When using dimensional analysis there always needs to be a 

• unit with magnitude.

• a conversion factor.

• a vector.

• a scalar.
