One of the pulley configurations makes the car go faster and the other reduces the speed of the car.ĥ.How can you measure the speed of an object? The larger the wheels, the faster the car will travel, if all other parameters are kept constant.Ĥ.What did you notice about the configuration of the pulley and its effect of the car’s speed? However, by the end of the lesson, pupils should be able to provide an accurate answer to the question.ģ What can you infer about the relationship between wheel size and the time it takes the car to move a set distance? This means that at the beginning of the lesson, pupils’ answers can be incorrect. This answer should provide prior knowledge regarding comprehension of the content. The colour of the car, brand, or driver experience should not be considered as potential elements for study.Ģ.What elements can influence the time required for a car to travel a certain distance as quickly as possible? The size of the wheels, engine power, gears, aerodynamics, and weight play an important role. There are many factors that can influence the speed of a car. 1.In what ways have cars have been improved to increase their speed?
