1 Overview Kinemaics: Descripion of Moion Posiion and displacemen velociy»insananeous acceleraion»insananeous Speed Velociy Speed and Velociy Speed & Velociy Velociy & Speed A physics eacher walks 4 meers Eas, 2 meers Souh, 4 meers Wes, and finally 2 meers Norh. Insananeous and Average Insananeous Speed - speed a any given insan in ime Average Speed oal disance divided by oal ime of ravel Insananeous Velociy Insananeous velociy is he limi of he average velociy as he ime inerval approaches 0. I is he insananeous rae of change of posiion wih ime. Insananeous rae of change is he derivaive which means slope of a graph a a poin 1

2 Acceleraion (m/s/s) The average acceleraion is he change in velociy divided by he change in ime. v() Insananeous acceleraion is limi of average velociy as ges small. I is he slope of he v() plo v() v Acceleraion Unis Speed/ime m/s/s = m/s 2 mi/hr/s = mi/hr-s km/hr/s = km/hr-s Disance/ime/ime or disance/ime 2 31 Acceleraion Slope of V_T Time (s) Velociy(m/s) Acceleraion Acceleraion is a vecor quaniy defined as he rae a which an objec changes is velociy. An objec is acceleraing if i is changing is velociy. Speeding Up & Slowing Down Posiion vs Time Plos Posiion a =3s, x(3) = 1m Displacemen beween =1s and =3s. x = x (m) 3 Average velociy beween =1 and =3 v = -3 (s)

3 Which plo bes represens a plo of velociy vs ime corresponding o he posiion vs ime? 1. A 2. B 3. C Acceleraion (m/s 2 ) The average acceleraion is he change in velociy divided by he change in ime. v() v A B C Insananeous acceleraion is limi of average velociy as ges small. I is he slope of he v() plo v() 31 Velociy vs Time Plos Gives velociy a any ime. Area gives displacemen Slope gives acceleraion. Velociy a =2, v(2) = Displacemen beween =0 and =3: =0 o =1: =1 o =3: Average velociy beween =0 and =3? Change in v beween =3 and =5. v = 3 v (m/s) -3 4 Acceleraion Unis Speed/ime m/s/s = m/s 2 f/s/s = f/s 2 mi/hr/s = mi/hr-s km/hr/s = km/hr-s Disance/ime/ime or disance/ime 2 Average acceleraion beween =3 and =5: a = The Ninja Speeding Up & Slowing Down The Ninja moorcycle can accelerae from 0 o 60 mi/h in 3.8 s. Wha is is average acceleraion? 15.8 mi/h/s 23 f/s/s or 7 m/s/s Negaive acceleraion can mean speeding up or slowing down. The same is rue wih posiive acceleraion. 3
