Choose how long the object is falling. If an object is projected upwards in a perfectly vertical Ask students to guess what the motion of a projectile might depend on? Is the initial velocity important? Is the angle important? How will these things affect its height and the distance it When thrown upward: the initial velocity a ball is thrown with is the maximum velocity of the motion and the velocity diwndles as the ball approaches the maximum height. If an object is merely dropped (as opposed to being thrown) from an elevated height, then the initial velocity of the object is 0 m/s. So, the ball's velocity is A ball is thrown downward with an initial velocity of 1 4 m s.
