You were in a tug-of-war contest which your team won. Write a letter to your friend that tells why your team won the contest. Remember to include unbalanced forces, potential energy, kinetic energy and net force. ***Your goal is to write an entire page/letter to a friend using the vocabulary provided and the knowledge you have about Force & Motion. *

How i would start it:

(i dont know any of the vocab. of Force & Motion)

Dear (name of friend),

Our team won because of strength as well as team work. Even though you're my friend, I would not go easy on you. It's a contest and when it starts I will act like I don't know you. Good job to your team!

This is only an idea you can change it a bit and the vocab.

Hope it helped :)
