Self-marked h/w questions (see previous post) - worked answers at the bottom of this post.
suvat recap questions found here Investigation: Measuring acceleration of free-fall by dropping balls Worksheet can be found here Key things to remember: Select a good range of heights (at least 6 of each); record raw data to the greatest level of precision you can (i.e. if recording height of 1 metre to the nearest cm, record this as 1.00 m); when calculating data always ensure number of significant figures is the same or one more than the data you are calculating from; repeat readings and take an average for each height to improve reliability; use as much graph paper as possible when plotting graph - select suitable scales to do this.
