What is the resultant of the combination of these two vectors?

• +2a

• 0

• -2a

• +a

Which statement describes a vector?

• It has magnitude but no direction
• It has direction but no magnitude
• It has both direction and magnitude
• It has constant magnitude but no
   direction

The horizontal component of a projectile's velocity is independent of...

• it's range
• time
• the vertical component
• none of these

In the absence of air friction, the vertical component of a projectile's velocity doesn't change as the projectile moves. 

• True
• False
• Sometimes true
• Sometimes false
