CSEC Integrated Science · May/June 2016 · Paper 2 · Question 4(b)(ii)

Carson tested friction by applying a 10 N force to a toy car on a smooth surface and on a rough surface, measuring distance travelled (Table 3).

State the formula used to calculate the energy converted (work done) when cars move.
