Answer Part 1: VelocityPart 2: AccelerationExplanationPart 1Velocity is a vector quantity. This means that velocity has both direction and magnitude. Velocity is defined as the change of distance with time in a specific direction. Part 2When velocity of a particle is changing, then it can be said that the particle is accelerating. Change of velocity with time is called acceleration.
