This is a study of modeling a falling object in liquid. We provide a video (in two versions - .mov and .mp4) which will enable you to collect data on a falling object in water to compare with your model and to estimate parameters using data you can collect from the video.
VIDEO Version 1 - CanisterFallInWater.mov
We have this version of the video which can be used for data collection and it is found here in this resource. This video will permit you to collect data and validate a model of a canister falling in a graduated cylinder of water.
VIDEO Version 2 - CanisterFallInWater.mp4
We have this version of the video which can be used for data collection and it is found here in this resource. The video is also available on the SIMIODE YouTube Channel. This video will permit you to collect data and validate a model of a canister falling in a graduated cylinder of water.
