EFFECTS OF NET FORCE ACTING ON A
TABLE
Try to push a heavy wooden table. Is a hard to push?
Are you unable to push it alone casily?
Ask your tend to belp you in push the table in the
same direction
Both of you together are able to push the table easily
This is because the force apphed by your friend is added to the
force exerted by you and the two forces act on the table in the
same direction
Now ask your friend to push the table from the opposite side
Does it move? If it moves, then in which direction does it
move
When you and your friend push the table trom opposite sides, the table doesn't move
if both of you apply force with equal magnitude. Let us assume that one of you exerts
a relatively larger force, what will happen? Why?
The table moves in the direction of force applied by the person who applies a
relatively larger force
All forces have both magnitude and direction. While adding the forces, the directions
of forces have to be taken into account. When forces act on a body along a straight
line and they are in the same direction, the net force is
taken as the sum of all forces acting on the body. To
adid forces, sign convention must be used. As shown
in the figure the force F, directed towards right could
be taken as positive and the force F; acting towards left could be taken as negative
Let the forces F, and F. act on the table in opposite directions as shown in the figure
and FPF Then F=F+ (-F2) F- F,​

Answer 1

Answer:

table will move if force applied is enough

Answer 2

Answer:

As the force increased to push the table than the mass of the table will decrease as it will be easy to push it
