MOTION

1. FORCE AND MOTION JHS 2

2. Understanding FORCE And motion Force is something strength Which result object Which imposed can experience change position or change form. Force can form pull or encouragement. Motion is change position or position to something point reference certain . Something object said move If object That experience change position to point certain as reference .

3. Connection between FORCE And motion Force pull or encouragement Which can influence circumstances something object. Force can give rise to change motion or change speed.Table Which pushed can move Because get FORCE push.So exists Force influence motion something object.

4. Tool Which used For measure big small style called dynamometer ,the unit isnewton (N). Force can influence circumstances something object,between other Force can cause: Object silent become move . For example moment push car strike , push table , interesting cart sand , kick ball, pull mine . FORCES

5. Object move become silent.On moment go on bicycle, when brake bicycle become slow And Finally stop.Means Force can cause object move become silent

6. Change form object.Example on moment happen crash car,car Can become changed the shape Because Force Which given on object exceed strength material object Which collide.Example other is moment use candle toy(plasticine).

7. Change direction motion object.Example on moment player ball heading ball, ball changed direction Because Force Which given on ball.

8. Proof that Force influence motion object can We do through model see saw, slingshot, And tractor spring. See saw See saw is A game in where board long And narrow pivot in middle, so that in moment Wrong One the end move go on so end another move down.

9. Slingshot Slingshot can used For throw rock. A slingshot usually made of from wood with two rubber Whichtied second his side.

10. TYPE TYPE STYLE Style Muscle Style muscle is style Which generated by power muscle . Example style muscle is on moment We interesting or push table , bring groceries Mother , And kick ball. Because happen touch so style This including style touch . b. Style Swipe between Two Object Style swipe is style Which happen Because touch it two surface object . Example style swipe is style Which Work on brake bicycle . On moment will stop , rubber brake on bicycle will come into contact with rim bicycle so that happen friction Which cause bicycle can stop when done braking . c. StyleMagnets Stylemagnet is style Which caused by pull or encouragement from magnet. Example style magnet is , interested nail when brought closer with magnet. Object- object can interested by magnet If Still is at regards Medan magnet

11. d. Style Gravity Style gravity is style Which caused by pull earth . Example style gravity is fall fruit from on tree with itself . All object Which thrown to on will still return to lower Because influence gravity earth . e. Style Electricity Style electricity is style Which happen Because Genre load electricity . Genre load electricity This caused by source energy electricity . Example style electricity is the move fan wind Because connected with source energy electricity . Payload electricity from source energy electricity flow to fan wind . So that , fan wind can move .

12. SPEED = SPEED =

13. 1. Speed Average Speed average defined as comparison displacement object with hose time Which required , whereas speed average is distance Which taken entirely shared with hose time travel . Speed average And speed average can formulated as following . V r = Vr = speed average, s = displacement , T = hose time 2. Speed Moment V moment = Lim V r = Vr = speed average s = distance t = hose time Speed moment often called with speed object .

14. Acceleration The thing that move with speed Which No constant will experience change speed in hose time certain . Object the said experience acceleration . The size acceleration or slowdown ( acceleration ) can determined with share change speed with hose time Which taken . a = = a = acceleration (m/s 2 ) Δv = changespeedAnd Δt = interval.

15. MOVE STRAIGHT Motion something object in trajectory straight named motion straight . A car drove in road kingdom Which straight is example motion straight . A student run surround field football Also is example from motion straight with four segment trajectory straight Which different on moment go through sides field Which different . Based on speed Which he took motion straight can differentiated become two that is Motion Straight Orderly (GLB) And Motion Straight Changed Orderly (GLBB).

16. REGULAR STRAIGHT MOTION In uniform rectilinear motion, objects cover the same distance in equal time intervals. For example, a speeding car covers a distance of 2 meters in 1 second, then in the next 1 second it covers a distance of 2 meters again, and so on. In other words the ratio of distance to time interval is always constant , or the speed is constant. In GLB, speed and speed are almost difficult to distinguish because the trajectory is straight, causing the distance and displacement to be the same. It can be formulated for GLB, that: v = Where : s = distance (m) t = time (s) v = speed (m/s)

17. S t Whereas speed always constant to time , the graph can depicted as following . v t On motion straight orderly increase distance Which taken to time can depicted in chart following This .

18. STRAIGHT MOVEMENT CHANGES REGULARLY motion straight changed orderly is motion object with trajectory line straight And own speed every moment changed with regular . Information : V t = speed end or speed after t second (m/s) V = speed beginning (m/s) a = acceleration (m/s 2 ) t = hose time (s) s = distance travel (m) Formula GLBB There is 3, that is :

19. PLEASE WRITE DOWN ON YOUR NOTE BOOK PAGE 20, I WILL TAKE THE SCORE FROM THAT. JUST MAKE A SIMPLE PICTURE AS YOU CAN UNDERSTAND. (FOR 15 MINUTES AND JUST 20 FASTER COLLECTOR YA)

20. FOR THE ONE WHO HAS FINISH, I WILL GIVE THE NEW PAPER FOR THE NEW SCORE LATER.
