A student investigates the energy transferred to thermal stores when a shoe is pulled across a rough, horizontal floor.
The student has a force meter and a metre rule.
Describe how the student should move the shoe and position the force meter while taking a reading.
State the two measurements the student needs to obtain.
Give the calculation the student should carry out to determine the energy transferred to thermal stores.
