We have been looking at various different forces for our science topic. We carried out an experiment and we’ve used different types of material such as: felt, sand-paper, plastic and carpet. We carried out this experiment because we wanted to know what fabric would carry the (toy) car further in distance. We did 3 different tests. Most peoples hypothesis were wrong because they thought that the car would travel quicker on plastic but it actually didn’t and the car traveled further on sand-paper. The reason why the car didn’t travel further on plastic was because the plastic was so slidy it moved forwards and backwards and also because there wasn’t a lot of friction between the 2 objects.
That’s such a good experiment. I would have thought that the plastic was so smooth the car would go the furthest distance. Well done P7
