Explain how the factors (upthrust, weight, density of fluid) influence whether an object will float or sink Use of mathematics ● Make calculations using ratios and proportional reasoning to convert units rates (1c, 3c). ● Calculate the differences in pressure at different depths in a liquid Calculate relevant values of stored energy and energy transfers; convert ● metres and joules (1c, 3c). Make calculations of the energy changes associated with changes in a ● selecting the relevant equations for mechanical, electrical, and thermal express in quantitative form and on a common scale the overall redistribution the system (1a, 1c, 3c). Suggested practicals Investigate the upthrust on objects in different liquids. ● ● Investigate the stretching of rubber bands.
