Question

The following is the distance-time table of an object in motion.

Time in seconds	Distance in meters
0	0
1	1
2	8
3	27
4	64
5	125
6	216
7	343

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?

Answer 1

a) Here, a = 0,

In this way acceleration is increasing

b) Since, acceleration is increasing. So net unbalanced force is acting on the object.
