Physics Sc1: ‘Bug-up’ Toy Investigation

Aim

The aim of this investigation is to ascertain the effect of weight on a child’s toy in relation to how high it will bounce.

Background

After playing with the toy, I looked at how it worked. It is a very simple mechanism that is shown above, consisting of a plastic base with a coiled spring wrapped around the centre. On top is a red rubber ‘sucker’ that grips to the base when you press down. The spring slowly forces the two apart and it then flies up in the air.

To find out the energy stored in a spring, you can just apply the equation for work done, replacing distance with compression. This way you get w.d.

mass x gravity x height. In this experiment the mass will be the variable, the height will be what is measured, and the gravity will remain constant. image01.png

Method

The method for this experiment will be simply to ‘arm’ the bug-up, and then get someone else to measure how high it flies using a metre ruler. Each time the experiment is repeated, a different mass will be used on the bug-up. To do this, I will need to remove the

Conclusion

Preliminary Investigation

For my preliminary experiment, I took a coil bound spring from the physics department and broke it by taking it beyond its elastic limit. After this I then hung it from a clamp stand and attached weights to the bottom and recorded the length of the spring. I then put the spring over the clamp stand and attached weights to the top to see if the compression was the same as the extension. These are my results:

As you can see, the results are perfect. They weren’t all exactly 100% exact, but they were close enough for the purposes of this investigation. This proves that the spring works exactly the same way whether you compress it, or extend it.

    However, the ruler was placed on the rim for simplicity which means the length of the tube at 1st resonance wasn't measured from 0 cm. At times when the tuning fork hit the rubber, the vibrations would end so fast that by the time it was placed above the tube

    There is minimal difference between the two as I would expect but as the load becomes heavier the equivalent loads in each experiment lead to a different extension, which I think is abnormal. Take for example 500g in the first experiment, there was an extension of 14.45cm but in the second experiment there was an extension of 15.75cm.

    I will then compress the spring at 1cm intervals and allow the trolley to pass through the light gate. The light gate will measure how long the piece of cardboard on top of the trolley cuts the beam of light for, allowing me to calculate the speed using the formula:

  1. An Experiment To Examine the Effect of Springs In Parallel

    (By increasing the number of springs and keeping the weight constant less, force will be acting on each spring, meaning less force will be acting on each molecule). Mathematically I would say the extension of springs in parallel is the original extension with just one spring divided by the number of springs that you are looking at.

    of particles, they are mediated / transmitted by particles called gauge boson. * The bosons carry the force between particles. I.e. electrons can exchange a photon with a neighbouring electron, leading to the EM force. The exchange particle is a virtual particle as it is not detected during the exchange.
