Practical exercise 1: PROPORTIONALITY IN NEWTON’S LAW OF GRAVITATION

Aim:

To show how the gravitational force is directly proportional to the product of the masses of two bodies and inversely proportional to the square of the distance between them. This activity can be also done in pairs.

Instructions for the teacher:

Print out Attachment1 and give a copy to each student (or pair) to fill in the missing values for F in the examples.

Instructions for the student:

The cartoon shows the dependence of the gravitational force on the masses of the bodies and the distance between them. The first two cases are already solved as an example. Solve the rest in a similar manner.
