... F = G m1 m2 / R 2 where R is the separation, and G is Newton’s gravitational constant: G = 6.67 x 10-11 Nm2/kg2 Gravity is very weak between objects on a human scale. In fact, it is the weakest of all known forces, by far. It is important only because it is always attractive, and is universal, so th ...

... At this ‘instant’, that is at the bottom, the motion can be modelled as uniform circular motion. The net force acting on her must be radially inwards. A Question 4 Solution Emma is correct and Frank is incorrect. The book is at rest, so, the resultant force on the book is zero. As a result N and ...
