Hi Everyone
Here are some pictures on my friction research with the heavy object.



Grass:
The grass was hard and easy. The friction on the rough surface made it a bit tricky though. I used a brick so it was quite hard.

Concrete:
The Concrete was smooth so it wasn't that tricky because friction won second best against my six pack (just kidding he he he)

Dirt:
Dirt was the hardest because as i went forward the dirt would pile up in front and make it heavier.
