A student is asked to carry out an experiment about the energy transferred when a
trolley is pulled across a table. The apparatus is set up as shown.
As the block falls it loses gravitational potential energy and the trolley and block
together gain kinetic energy. The student is asked to find out what fraction of the
gravitational potential energy becomes kinetic energy.
The student writes an outline plan for an experiment and produces a table.
Add more detail to improve this plan. You should do the following:
complete the table,
add a line to the diagram to show the distance d,
describe how you would measure d accurately (you may add more to the diagram if
describe how you would make each measurement of t accurate,
comment on any safety aspect of this experiment.
