Force of Friction
Friends, the principle
of friction is very straight and simple, according to this principle when we
rub an object on another object then it makes 2 forces. First is that which
caused by rubbing these object and other is that which works against that particular
force and this force is called Force of Friction. Friction force is like an
anti-force that works in the opposite direction of the natural force always.
This is the force, which makes every moving object to stop, if there will be no
friction force then a moving object will neither stop nor its speed will be
reduced. Today we are going to teach you about this friction force by using
matchstick experiment. CLICK HERE TO KNOW How to Make Non Electric Hand Pump at Home ...

Matchbox
will Teach us About Force of Friction
|
Material Required :
- An empty Matchstick
- Cotton Thread
- Cello Tape
Principle : Force of Friction
Experiment :
· Step
1 : Take an empty match box first and then remove its inner parts. Now
make 1-1 hole in the longest sides of that inner part and place
1 matchstick through them.
· Step
2 : Now make 1-1 in the small sides of matchbox’s inner part as well.
· Step
3 : After this take a cotton thread and sew it through the holes. Make
sure that thread should go over the matchstick.
· Step
4 : Now close the matchstick and cover it with cello tape so that matchstick
can’t move. With that make knots on the both side of thread as well.

| Theory of Friction Force |
Now hold this matchstick
as shown in the figure and let the matchstick move towards downward. When
matchstick comes arrive at a point then pull the thread, this will stop the matchstick
at that same place and matchstick will not move forward. But as you again lose
that matchstick, it will move again downward. The only reason behind the
stopping of matchstick box is friction, which cause due to the tightness of
thread and matchbox. Hopefully, now you have also understood about the force of
friction, if you have doubt then try this practical at home now, your doubt
will be removed.
