What is neither one.
100
The path that a projectile takes. This is shaped as a parabolic curve.
What is a trajectory?
100
This is how two vectors would have the GREATEST resultant.
What is they would point in the same direction.

What is 6 x 10 o meters?
200
This is the slope of the displacement-time graph.
What is velocity?
200
This is the initial velocity for any object in freefall.

What are distance and time?
300
This is an approximate width of a sheet of paper.
What is 10 -4 meters?
300
This is the slope of the velocity-time graph.
What is acceleration?
300
This is the name of the projectile vector that deals with its motion in freefall.
What is the "y" or Ay vector.
300
This is what happens when a ball is thrown as a projectile from a cliff and when a second ball is dropped from the same cliff at the same time.
What is they hit the ground at the same time.
300
Of these, the only vector quantity is this: velocity, time, distance, speed
What is velocity?
400
This is the approximate weight of a stick of butter, and is 1 kg m/s/s.
