So today I think I will tell you about physics. First I will tell you about force. Or power. There are many kinds of power on Earth. Electric power, frictional force, magnetic force, and elastic force. It is all important. If Electric power is gone, we can't use bulbs and batteries. If frictional forec is gone, all of the floor all almost same as ice. No more slipery than ice. So If we slide down we can't stop until we crash to something or crash at someting. So I think force is very important. So first Electric power is electricity. frictional force is like force that stop making ground slipery. Magnetic force is force that magnet had made. elastic force is just like rubber band. If you stratch it, it come back into normal size. There are also other many kinds of force. Like gravity. I will talk about this gravity later. When I'm going to talk about Isac Newton. Did I mention it that, Newton made three rule of physics. Like F=ma, but it is other story so good bye~ 답변자 tc0073 답변일 2012-09-26 답변내용 Yesterday, I was talked about Water's three states. So today I think I will tell you about physics. >>Yesterday, I talked about water's three states so today I think I will tell you about physics. (unnecessary word) First I will tell you about force. Or power. >>First I will tell you about force or power. (sentence construction) There are many kinds of power on Earth. Electric power, frictional force, magnetic force, and elastic force. >>There are many kinds of power on Earth like electric power, frictional force, magnetic force, and elastic force. (sentence construction) It is all important. >>Those are all important. (choice of word) If Electric power is gone, we can't use bulbs and batteries. >>If electric power is gone, we can't use bulbs and batteries. (capitalize proper nouns only) If frictional forec is gone, all of the floor all almost same as ice. No more slipery than ice. So If we slide down we can't stop until we crash to something or crash at someting. So I think force is very important. >>What do you mean? So first Electric power is electricity. >>Electric power is known as electricity. (intended message) frictional force is like force that stop making ground slipery. >>Frictional force is like a force that stops making the ground slippery. (capitalize the first letter of the first word in the sentence) Magnetic force is force that magnet had made. >> Magnetic force is a force that magnet had made. (lack of article) elastic force is just like rubber band. >>Elastic force is just like a rubber band. (capitalize the first letter of the first word in the sentence / lack of article) If you stratch it, it come back into normal size. >>If you stretch it, it comes back into its normal size. (spelling / subject-verb agreement) There are also other many kinds of force.Like gravity. >>There are also many other kinds of force like gravity. (word order / sentence construction) I will talk about this gravity later. >>I will talk about gravity later. (unnecessary word) When I'm going to talk about Isac Newton. Did I mention it that, Newton made three rule of physics. Like F=ma, but it is other story so good bye~ >>When I talked about Isac Newton I mentioned that, Newton made the three rule of physics like F=ma, but it is another story so good bye~. (verb tense:past tense) Thanks for writing! I hope next time you would talk about yourself.
