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

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

Acceleration is...

• Time/Position

• Change in Position/Change in Time

• ΔV/ΔT

• Position x Velocity

39 m/s could be...

• velocity (v or v_o)

• acceleration (a)

• time (t)

• change in position (Δx)
