2.2 Newton’s First Law of Motion
Each year in Canada there are more than 150 000 traffic collisions resulting in
over 200 000 injuries and almost 3000 deaths. Of these deaths, the greatest
number in any single age category is the 15-to-25-year-old group. Although the
average number of deaths on Canada’s highways has decreased in the past 20
years, there is still a great demand for improvement on safety.
Sadly, many of the deaths and injuries could have been prevented so easily,
simply by wearing seatbelts or by using airbags.Understanding Newton’s first law
of motion will help you appreciate how wearing a seatbelt could improve safety.
UPD: черт, перепутал, всё-таки это был учебник 20-летней давности. Т.е. уже тогда этот маразм уже начинался понемногу. Ну ок, сейчас посмотрим что в современном на эту тему.
Современный тоже так ничего, там ещё и фотку добавили для наглядности:
Every year in Canada, there are about 160 000 car accidents. These accidents cause
many injuries, and about 3000 are fatal. Many of these injuries and deaths involve
motorists who are not wearing seat belts or are driving too fast. An understanding of
Newton’s first law will help you appreciate the importance of safety features in cars
such as seat belts and airbags. Figure 1 shows a crash test designed to help engineers
test and improve the safety features of new cars. What will happen to a crash test
dummy during a collision if it is not wearing a seat belt and no airbag is present?
Newton’s first law will help us answer this question.

Это напоминает, как при совке в предисловии к любой научной работе надо было обязательно помянуть решения XXXXXXVVVIII съезда КПСС и желательно процитировать тов. Сталина/Хрущёва/Брежнева.
В этих учебниках нормально изложенная физика с какой-то страницы всё-таки начинается?

Date: 2021-08-08 01:02 am (UTC)Примерно такой же (компромиссный) подход наблюдается и в современном канадском курсе, вот только понятие о законах Ньютона даются в 11-м классе, а понятие о инерциальных системах отсчета, как и вообще об относительном движении и системе отсчета — в последнем 12-м. Возможно, лет через 10 вообще эту тему выкинут из учебника из-за её сложности.
