Question

to break a wooden table why do we need additional force​

Answer 1

Answer:

coz its particles are very much closer to each other so it is difficult to break it easily so we need additional force to break it.

Answer 2

Answer:

The table must exert an upward force to prevent the dog food from falling through the table. Strangely, if a heavier object is placed on a table, the table must exert more normal force to prevent the weight from passing through the table.
