If the acceleration is negative and the velocity is also negative, the speed of the object increases.Deceleration: It means a reduction in speed or a slowing down. Some confusion is there between deceleration and negative acceleration. Negative acceleration can increase the speed of an object.
Displacement The displacement x of a particle is the changein its position:x x 2 x 1. (2-1)Displacement is a vector quantity. It is positive if the particle hasmoved in the positive direction of the axis and negative if the xparticle has moved in the negative direction.verage Velocity When a particle has moved from position x 1 to position x 2 during a time interval t t 2 t 1 ,its average velocity during that interval is(2-2)The algebraic sign of v avg indicates the direction of motion (v avg is avector quantity).
