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.

You and a friend (alex) are at a a tree-top adventure park .. . part of the course requires you to climb up a rope. you both climb the same rope in the same amount of time. however, the tension in the rope is greater when alex climbs. who did the most work? alex did - more tension means more force - more force means more work was done you did - less tension means less force - less force means more work was done to find the work done, the force exerted and distance moved are multiplied. a couch is moved twice before you are happy with its placement. the same force was used to move the couch both times. if more work is done the first time it is moved, what do you know about the distance it was moved? when more work was done, the couch was moved less. when more work was done, the couch was moved further. when more work was done, the couch wasn't moved at all. when more work was done, the couch was moved the same distance.
