$\LARGE\sf{\underline{\underline{\blue{Required\:answer:}}}}$

⌦ Slope of a velocity time graph gives the Acceleration

⌦ Velocity is a vector quantity

⌦ The speed of body is continuously decreasing then the body said to be in decelerating motion

⌦ Distance is defined as the magnitude and size of displacement between two positions or amount of space between two object

⌦ SI unit of acceleration is metres/second²

⌦ Unit of velocity is metres per second
