4. In Part 2 of the lab, did the drop time of the ball depend on the horizontal velocity? Explain your answer with
data from the experiment. If you had variations in drop times, what could account for those? What
generalization can you make about horizontally moving projectiles?

The time of motion of the ball from the vertical height is independent of the horizontal velocity.

Horizontal moving projectiles is not affected by gravity and the initial velocity is equal to the final velocity.

The time of motion of ball dropped from a vertical height is calculated as follows;

[tex]h = v_0_yt \ + \ \frac{1}{2} gt^2\\\\[/tex]

where;

  • h is the vertical height
  • t is the time of motion
  • g is acceleration due to gravity
  • [tex]v_0_y[/tex] is the initial vertical velocity

From the equation above, we can conclude that time of motion of the ball from the vertical height is independent of the horizontal velocity.

If there is variation in drop time, it could be as a result of applied force when the ball is dropped. This applied force influences the initial velocity which in turn alters the drop time.

Generally, horizontal moving projectiles is not affected by gravity and the initial velocity is equal to the final velocity.
