Physics Acceleration of Gravity Using a Pendulum

Physics Acceleration of Gravity Using a Pendulum Questions

Activity 2: Discussion (10pts)

Build an imaginary planet and find its acceleration of gravity using a pendulum. Please work to invent a new planet. Calculate the acceleration of gravity on that planet and determine how long the pendulum's period is on that planet.

1. craft a planet:

a) Write the Planet mass: Mass is _____ times the earth's mass.

Example, the planet's mass is 3 times the earth mass ->-> ???????????????????????????? = 3?????????????????????

b) Planet radius is _____times the earth's radius.

Example, the planet's radius is 1/2 times the earth radius ->-> ?????????????????????????? = 1 2 ?????????????????????

2. Read section 6.5 of your book, Newton Universal Law of gravitation. In this section, you learn about the relation between the acceleration of gravity on the ???? earth, ???? = 9.8 2 and the earth' s mass and radius. This relation is valid for any ???? planet. Using your new data of mass and radius, find the acceleration of gravity on your new planet. Show all the steps. Discuss all together the accuracy of your calculations.

g= _______________

3. Using the pendulum formula for the period of oscillation, and your new acceleration of gravity, determine the period of a pendulum that is 1 meter long and it is on this planet.

Show all the steps and all the work to find the period expressed in seconds.

4. As the last part, you are tasked to find a name for your planet. Then explain which sport would be easier to do on this planet, if any, and explain the advantages or disadvantages of the new acceleration of gravity.
