- 3. PROJECTILE MOTION isany motion that is solely affected by the pull of gravity Free-fall Horizontal Projectile Projectile at an angle • The object is moving in one dimension only (vertical) • The angle of release is 90° from the horizontal. • The object is moving in two dimensions. • The angle of release is 0° from the horizontal. • The object is moving in two dimensions. • The angle of release is above 0° but below 90° from the horizontal.

What have you noticed on the magnitude of horizontal velocity in each point? Is there a value for initial vertical velocity? What happens to the vertical velocity of the projectile as it moves upward? What happens to the vertical velocity of the projectile as it reaches its highest point? What happens to the vertical velocity of the projectile as it moves downward?
