From the 11th March-16th March it is science and engineering week. Primary 4-7 are all taking part in a whole week of science and all the activities we do is about forces. The first thing that we learned was Newton’s 3 laws and they are very important because they describe forces very well. The first law is “when forces acting on an object they are balanced,it will remain at rest or move in an straight line at constant speed”. The 2nd law is “force=mass x acceleration”. The 3rd law is “every action has an equal and opposite reaction” and that is Newtons 3 laws.
