Newton said what goes 1You climb up the slide and sit down. up must come down.He You are ready to go.Are you sliding down?No,not yet.Things stay talked about gravity ().still unless something makes them.It is Newton's First Law. Slides work because of So you have to give yourself a push to start the journey down. gravity.But that is not all. 2Now you are sliding down. Do you feel you are slowing down a little?When two things rub( 擦)against each other,they cause friction(摩擦力).Without friction, you will slide down faster and faster to the bottom.That is more interesting,but more dangerous. At the bottom of the slide,you come to a full stop. Your feet touch the ground and add more friction.Newton's First Law also says moving things keep moving unless something makes them stop.So if you do not use your feet,you'll fly off the slide. )1.Which word can be put in A.stop B.fly C.move )2.Which picture explains why you slow down a little when sliding down? push friction pull A B C )3.What makes you stop at the bottom of the slide?
