Propulsion

In this activity, students consider energy transfers and calculate work done, speed, power and efficiency in order to compare two RNLI lifeboats in a rescue situation. They then go on to explore how much energy can be saved by restricting the speed during non-emergency situations. Students work out how the power output, energy out and amount of fuel used will change if the engine force is reduced. The worksheet provides the formulae and tables for students to complete.
