(a) What conclusion can you draw about the acceleration? Is it constant? Increasing? Decreasing? Or Zero?
(b) What do you infer about the forces acting on the object?
Solution
(a) The above table shows that the motion is accelerated and acceleration is increasing uniformly with time.
(b) As the acceleration is increasing uniformly, the force acting on the body is also increasing uniformly with time.
