Today,for science,i learn a topic related to Forces.It is no other than Friction!
About Friction,i think it happens when two or more things rub against each other.It produces heat energy.I also thought about it.When things are slippery,it seems that friction is reduced!MC also showed us some videos on Friction.It was very interesting.The P group performed a little ''advertisment''.Its was about some good and bad advantages about friction.
My group thought of some ideas.I am pretty nervous.I NEVER ever,wanted to be the ''advertiser',but other than me,none wanted to be it.
I want to be like a professional,but i am not sure how!?
Can u give me some tips?By the way,when can u use your comp? I want to know please.
