1. What does it mean for an object to travel in two dimensions? 2. Describe what happens to the horizontal component of velocity while an object is in the air. 3. If an object travels at a constant velocity, how does its average velocity compare to its instantaneous velocity throughout the trip? 4. Which equation will you use to make calculations about a projectile's horizontal displacement (i.e., range) and horizontal velocity? 5. What three equations can you use to make calculations about a projectile's vertical motion? 6. Sketch the motion of a horizontally launched projectile on the axis below
