Vertical Displacement Lab Report
Limitations
The angle of release is hard to control, instead of using two ruler that form a 90 degree, a protector should been used
Exact landing spot of the ball on the ground, it’s hard to point out a highly accurate landing spot. Powder should be used, in which it can leave a mark.
The measurement for the vertical displacement, the handmade ball catcher is suspended with light string, as the collision occur, the ball catcher starts to rotate in circular until it reaches the maximum height, this can increase or decrease the measurement of height and make it harder to record the precise measurement for vertical displacement.

My hypothesis regarding to the two experiments are proven correct. As the height of release increases, the horizontal displacement also increase squared, as shown in figure 7. As the mass of the ball catcher increase, the vertical displacement of the system decrease proportionally, as shown in figure 8. The percentage difference between the initial velocity calculated with kinematics and momentum are 0.0515%, which shows the calculation of initial velocity using the two different ways have a relatively similar answer. The percentage error between the theoretical value of initial velocity measured with photo gate and lab quest and the experimental value calculated with kinematics is 0.02473%. The percentage error between the theoretical value of initial velocity measured with photo gate and lab quest and the experimental value calculated with momentum is 0.07628%. Both of the percentage error is relatively small, which prove that the experiment result is valid. The experiment displays the real world context of shooting, in which conservation of momentum and energy and collision are
