# Q A1.     The following is the distance-time table of an object in motion:                  Time in seconds  Distance in metre 0 0 1 1 2 8 3 27 4 64 5 125 6 216 7 343 (b)      What do you infer about the forces acting on the object?

S Sanket Gandhi

i)Velocity is the change in distance with time. So the velocity is increasing non uniformly, so the acceleration increases with the time.

$F\ =\ ma$

ii) Thus the net force acting on the body is also increasing.
