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.
