How road safety has changed over the years Why Speed Limits Have Changed During the last 100 years speed limits have changed in the UK‚ now in residential areas speed limits are generally 20mph to 30mph and on main roads the speed limit is 40mph. On the motorways the speed limit is raised to 70 mph. The first speed limit was 1865; this speed limit was 2mph in built up areas such as cities‚ towns and villages. This was then raised to 20mph and large fines were put in place for speeding and

Module 1 Physics: The Basic Science What this module is about The study of science has two branches namely‚ the life sciences and the physical sciences. The life sciences include biology‚ zoology and botany. The physical sciences branch into areas such as geology‚ astronomy‚ chemistry and physics. However‚ physics is more than part of physical sciences because it does not only deal with matter and energy but it also deals with the other basic concepts like motion‚ forces‚ heat‚ sound‚ light

We varied both the accelerating force and the mass of the glider. We found that for a given force the acceleration of the glider was inversely proportional to the mass of the glider
