Reflection: Developing a Conceptual Understanding Free Fall on Planet Newtonia - Section 2: Free Fall on Planet Newtonia


Since my students did so well with this activity, I thought that next time I could change it up by having different groups do the problems finding the acceleration due to gravity on different planets. This would be another opportunity for students to whiteboard and explain to the class how they got acceleration and how that acceleration represents the increase in velocity each second. I think that would make it more real-world for them since it would be actually about planets that they have heard of instead of a made up planet, like Newtonia. With this activity they will be able to see that the acceleration due to gravity is different on each planet. But on all of the planets objects experience the same free fall characteristics: an object falls a larger distance each second and the object increases its speed the same amount each second.

Free Fall on Planet Newtonia

Unit 3: Uniform Acceleration Motion
Lesson 9 of 14

Objective: Students will be able to state the value of the acceleration due to gravity in meters per second squared and use it in mathematical models of free fall.

Big Idea: Students find the accelerations due to gravity for different planets.
