Answer to Question #220594 in Physics for ran li

Question

The lab question

Part 2a: FgFg vs m1m2

How is gravitational force (Fg) related to the magnitude of the mass of two masses (m1 and m2)?

Essentially you are validating Newton’s Law of Universal Gravitation Law that is modelled mathematically as:

m1(kg)=

m2(kg)=

m1m2(kg)=

r(m)=

Fg(N)=

Part 2b: FgFg vs r

How is gravitational force (Fg) related to the separation distance* of two masses (m1 and m2)? *The separation distance is defined as the distance between the centers of the two objects; the best strategy involves centering the objects on a gridline and using distances that are a whole number of squares.

Using the interactive collect 7-10 data points in order to answer the question above. Complete a data table below and graph the data in order to describe the relationship between gravitational force and the separation distance.

separation distance(kg)=

Gravation force(N)=

Answer 1

Part 2a

The gravitational force (F_g) related to the magnitude of the mass of two masses in the following way:

$$F_g=G\frac{m_1m_2}{r^2}.$$

Part 2b

The solution is provided below:
