Motion Part A2 Flowing Water

 

 

 

All you are really doing is measuring the time it takes to fill the beaker. But, you are doing it in increments. You first run the water at a constant flow (slow), put the beaker under the water at the same time you turn on the stop watch. When the water hits the approximately the 1/4 marks pull the beaker out of the water and stop the stop watch. This is the time for trial 1.  Leave the water running and reset the stop watch. Measure the water level of the top of the water in the beaker. This is your distance reading for trial 1 (x1).

 

Put the beaker back under the water at the same time start the stop watch again. When the beaker hits about 1/2 full, pull out the beaker and stop the stop watch. Measure the distance from the bottom of the beaker to the top of the water in the beaker to obtain the distance for trail 2 (x2).

 

 Put the beaker back under the water at the same time start the stop watch again. When the beaker hits about 3/4 full, pull out the beaker and stop the stop watch. Measure the distance from the bottom of the beaker to the top of the water in the beaker to obtain the distance for trail 3 (x3).

 

Subtract your starting point of 0 from your first distance reading x1. Then divide this distance by the time taken to go that distance to obtain the speed of the water for trial 1.

 

Subtract your distance reading x1 from reading x2. Divide this distance by the time taken to go that distance to obtain the speed of the water for trial 2.

 

Subtract distance reading x2 from x3 to obtain the distance for trial 3. Divide this distance by the time taken to go that distance to obtain the speed of the water for trial 2.


After obtaining the speeds for trials one, two and three obtain their average.
