The following is the distance-time table of an object in motion:
Time in seconds | Distance in metres |
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?
The data in the table shows the distance covered by the object at any time interval.
(a) It clearly shows that the distance covered at any time is than the previous time intervals. Therefore, the acceleration of the object is .
(b) As per the second law of motion, we know that
Here the mass of the object remains , the acceleration shows that the force acting on the object is as well.
