1. v In the study of kinematics, we consider a moving object as a particle. Displacement Kinematics in One Dimension (Phy 2053) vittitoe

2. 0246 2 4 6 x Displacement The displacement of a particle is defined as its change in position. (m) x = x x o = 6 m 2 m = 4 m (West)

3. 0246 2 4 6 x The displacement of a particle is defined as its change in position. (m) x = x x o = m m = m (west) Displacement x = x x o = m-2m = - m (East) distance =? ….travels 2m to 6m = 4m, then travels from 6m to -4m, which is 10m Total distance x = 14m

4. 0246 2 4 6 x The displacement of a particle is defined as its change in position. (m) x = x x o = ( m) ( 6 m) = 8 m (west) Displacement
