Question

if you repeated this experiment, which options could lead to more precise results? check all that apply.
increase the drop heights from the top of a building, using the same lever.
use a video camera to record the height of each beanbag with greater accuracy.
use a pressure sensor to record the force of the soda bottle more accurately.
increase the number of trials for each experiment by a factor of three.
increase efficiency by examining mass and speed at the same time in the same trial.
throw the bottle at the lever as hard as you can, instead of dropping it, to create maximum ke

Explanation:

• Using a video camera to record the height of each beanbag with greater accuracy would improve precision as it can capture more detailed and accurate data compared to manual observation.
• Using a pressure sensor to record the force of the soda bottle more accurately would give more precise force measurements.
• Increasing the number of trials for each experiment by a factor of three would allow for averaging out random errors and give more reliable and precise results.

Increasing the drop heights from the top of a building using the same lever may not necessarily lead to more precise results as it could introduce other variables like air resistance more significantly (assuming it's a free - fall experiment). Examining mass and speed at the same time in the same trial may not improve precision as it could complicate the measurement process. Throwing the bottle at the lever as hard as you can instead of dropping it would introduce an inconsistent and hard - to - control variable (the force of the throw) rather than improving precision.

Answer:

Use a video camera to record the height of each beanbag with greater accuracy, Use a pressure sensor to record the force of the soda bottle more accurately, Increase the number of trials for each experiment by a factor of three.
