That's great thanks, really helpful thanks for your help :)

Ok thanks for your help. You say E is lowered slightly, do you think it would be possible to observe a measurable change in E using quite standard equiptment?

Calculate how far it has fallen in 8 seconds. Then calculate how far it has fallen in 9 seconds. If for example in 8 seconds it has fallen 200m and in 9 it has fallen 250m then the distance is 50m. But if your distance at 9 seconds is over 324m then it will have hit the ball between the 8th...

I am investigating the Young's Modulus of certain materials and what factors have an effect on the Young's Modulus of materials. I am going to be altering the temperature, my hypothesis being that increasing the temperature will lower the E of the materials. Are there other factors I could...

2pi equals 360 degrees and pi/2 is 90 degrees. A sine and cosine function will be the same value if you add or take away 2pi as it is the same as adding or taking away 360 degrees and since the functions repeate every 360 degrees there will be no difference. But be aware if the value inside the...
