<h3>2 Answers:</h3>

a) Velocity is a vector quantity

e) Velocity is a speed with direction

=================================================

Explanation:

If we know the velocity of an object, then we know how fast it's going (speed) and where it's going (direction). It is a vector because the direction of the vector determines the direction, and the length of the vector (aka magnitude) determines the speed. So in a sense we've built in two facts of data into one visual.

An example of velocity: 10 miles per hour north. Here we have the speed of 10 mph and the direction north.

-------------------

Extra info:

  • Choice B contradicts choice A, so we can cross choice B off the list.
  • Choice C is false because speed is a scalar, or single quantity, and not a vector. As mentioned earlier, speed is a part of velocity, but they aren't the same exact thing.
  • Choice D is false because the velocity does not account for net force. We don't have any force information built into the velocity.
