Introduction

When water flows from the reservoir (bottle) to the end of the pipe PE is converted to KE, this causes the water to squirt out of the pipe with velocity v falling in the parabolic path shown in the diagram below.

Theory

Applying the law of conservation of energy to a mass m of water

image01.png

The water falls with uniform acceleration, applying the equations of uniform acceleration to the vertical motion:

The horizontal velocity of the water is constant therefore:

Substituting for t gives

Substituting into the energy equation gives

Method

By measuring the height of the top of the water in the bottle and the distance squirted by the water confirm this relationship and find y.

Conclusion

After all, the practical is done with some errors and mistakes that are clear in the graph, and I think this graph can be made a lot better if we use the suggestions above or similar ones.

  1. Analyzing Uniform Circular Motion

    This is due to a systematic error. The R^2 value is close to 1 which means that the random error is eliminated and this is done through averaging. The actual slope gained from plugging in the controlled/constant values for this experiment is: Slope = ; where the accepted value of g is assumed to be 10ms-2.

    Controlled variable: the slope/gradient at which the curtain track is placed at, height adjuster, by not changing the slope or height at the end of the slope, this has to be kept constant or else it will not be a fair test, also the type of the ball (keep and use the same ball), and the track 2.
