Figure shows four paths along which objects move from a starting point to a final point, all im the same time interval. The paths pass over a grid of equally spaced straight lines. Rank the paths according to the average velocity of the objects.

Abody of weight 60 kg is standing in a lift the lift going upward with a uniform velocity of 4.9 metre per second slows down and stops in two seconds then apparent weight of the body during the slow down process is

Velocity is a description of both speed and direction, therefore it - a vector - a force arrow - the same as acceleration - a magnitude
