# Converting Gravitational Potential Energy to Kinetic Energy.

Extracts from this document...

Introduction

Physics Coursework: Converting Gravitational Potential

Energy to Kinetic Energy

Apparatus

Method

A ball bearing is released from the top of the v-shaped runway. When it reaches the bottom of the runway it should roll along the bench at a constant speed. The speed, v, will be found by measuring the time it takes for the ball bearing to travel a distance of 1m, hence the metre rule. To improve accuracy, 3 measurements of speed at each height will be taken. In order to construct a good graph the results of at least 6 different times should be used.

Prediction

I predict that by increasing the height of the v-shaped runway, this will increase the amount of gravitational potential energy lost, and increase the amount of kinetic energy gained.

Middle

There were a few problems in recording results for this experiment, and if this experiment were to be repeated in future, some alterations would be necessary to make the results more realistic and conform to the expected results.

If the ball did not roll along the bench in the right direction, after leaving the runway, it would fall off the bench and another measurement would have to be recorded because if the ball does not roll along the bench, the measurement would be void. The subject on the stopwatch who was stopping the watch when they felt the ball pass the metre rule may not have been accurate with their

Conclusion

Another possible fault with the recording measurements part of this experiment was that it would have been more efficient and accurate to use a “speedometer” to find the speed at which the ball is travelling at, instead of recording the time it takes to travel a certain distance. A “speedometer”, presuming it would be electrical and more technological, may produce more accurate results and give a better understanding of how increasing the gravity of an object, in this case a V-shaped runway, actually effects the object being released from it.

These are problems, which can be solved if we performed the experiment again, and would perhaps give more accurate results.

my ability: The mass of the trolley: Mass is included in the formula for Gravitational potential energy so I will use the same trolley throughout the experiment. Other factors may hinder the results such as friction. Friction between the wheels of the trolley and the ramp will convert some of the potential energy to heat.

I noticed a significant drop in the tennis ball. It decreased 7cm whereas the other balls only decreased by 4cm or 5cm. The tennis ball is highly compress-able and has little internal pressure. As the ball drops the gravitational energy is converted to kinetic energy.

This is because of the reactants used in the fusion process which are easily accessible. In great contrast to fossil fuels, huge amounts of money would have to be spent on large equipments in digging deeply into the earth to acquire the energy.

2. ## Find the realtionship between gravitational potential and kinetic energy

The difference between kinetic energy and potential energy, and the conversion of one to the other, is demonstrated by the falling of a rock from a cliff, when its energy of position is changed to energy of motion. Another example is provided in the movements of a simple pendulum.

We then repeated the measurement two more times to obtain an average time to make the results more accurate. * We then increased the height (h) in steps of about 2cm, each time taking three measurements of the time taken for the ball bearing to roll 1m along the bench.

I will try making this a fair test by using the same ball so that it is the same size, weight and texture, the same ramp and bench area so if there are any faults it will affect the results each time.
