## GCSE Physics

**Calculating ‘g’ the force due to gravity using a pendulum.**

**Welcome to A Level Physics! Physics is all about explaining why things happen. We all know that when you drop a ball it falls to the floor due to the gravitational force acting on it. But what is the value of that gravitational force?**

In order to find out the value for ‘g’, the gravitational force on Earth, you can do a simple experiment, plot a graph and do a bit of maths. (see how to plot graphs and work out errors attached). Investigate other methods of finding g. Which method is the best and why?

This project will test your ability to conduct an experiment, draw a graph and interpret the results. It will also give you an opportunity to develop your ability to reflect on your work and determine what you need to do to become even better than you currently are.

Enjoy the task and remember to tell your friends how you were able to determine ‘g’, the gravitational force due to gravity with just a bit of blue tack, a piece of string and a watch.
