Homework Statement As part of my coursework, I need to be able to prove the formula for the time period of a simple pendulum. I know what the formula is but I really don't know how to prove it. I would appreciate any help. Homework Equations T = 2*PI*Root(l/g) The Attempt at a...

I am doing a school project to investigate how gravity varies over the Earth's surface. I understand that the force is weaker at the equator due to the Earth's rotation but there are a few things that I don't quite understand: 1: Firstly, why is an object on the Earth's surface only affected by...

It really is just one set of data from one experiment showing the height of the ball at various times (just over 5 seconds which relates to about 8 bounces of the ball).

ive got to perform some calculations on data we've been given about a bouncing ball. the problem is i can't think of anything interesting to try and calculate (acceleration due to gravity and loss of energy on each bounce being about all i can think of).

Coursework ideas?? Hi everyone, For my AS physics coursework we have been given some data for a vertically bouncing ball (i.e. distance and time) and I was wondering if anyone could think of anything remotely interesting to do with it?? Thanks in advance

All i want to find out is the approximate stress for each step that a person takes. I need to keep it quite simple for a presentation that i am doing so i was going to try and estimate the force that is produced on impact with the floor and then divide that by the approximate cross-sectional...

Can anybody give me the equations the equations for displacement and maximum surface stress in a beam fixed at both ends and the load in the centre?

Homework Statement Can anybody help me calculate the approximate force/ stress on a hip joint during walking and/or running Any help is greatly appreciated. Homework Equations The Attempt at a Solution

The golf club idea sounds excellent but can anybody help to do the calculation? Any help is greatly appreciated

Homework Statement I have been asked to make a presentation about a material for my AS coursework. I have chosen to talk about titanium and its use in sport. The only problem is, we have to do some sort of calculation which involves elastic modulus/ hardness/ tensile strength etc. I was...

I have been asked to make a presentation at school about titanium and I have decided to do it with respect to its use in sport. The only problem that I am having is with trying to do some sort of calculation to calculate the required elastic modulus/ tensile strength/ hardness value required for...
