Lab Two – Acceleration Due to Gravity Acceleration Due to Gravity Gravity Acceleration Value for Upper Graph – A = 4.04 2 ∗ 4.04 = 8.08 m / s 2 ± 2.6 Gravity Acceleration Value for Lower Graph— m = 9.25 m / s 2 ± 0.17 Gravity Acceleration Percentage Error (Upper Graph) 8.08 − 10.68 9.8 ∗ 100% =− 26.531% Gravity Acceleration Percentage Error (Lower Graph) 9.25 − 9.42 9.8 ∗ 100% =− 1.734% Lab Three—Projectile Motion Pfent, Alexandra Projectile Motion Lab Partner: Rameses Acosta Vertical distance h (m) = 1.016m Trial Horizontal Distance x (m) 1 0.073m

2 0.05m 3 0.097m 4 0.09m 5 0.122m Average x value = 0.0864m Initial Velocity of the Ball – vi = 0.0864 ∗ √ ( 9.80 m s 2 2 ∗ 1.016 m ) = 0.19 m / s 1. What effect does the force of gravity have on the horizontal velocity of the projectile? Explain. The force of gravity does not impact the horizontal velocity of the projectile. This is because there is no horizontal force acting upon the projectile, so only the vertical velocity of the projectile is impacted. 2. What effect would air resistance have on the range of the projectile? The absence of air resistance would increase the range of the projectile, since the projectile would not feel drag force working against it. Drag force slows down a projectile.
