FRICTION FORCE EXPERIMENT: A MAGIC CHOPSTICK

The main aim of this experiment was to find out the FRICTION FORCE.

We had two bottles, A and B. First we filled bottle A and bottle B with rice; but, in bottle B we made more space for extra rice (tapping the bottle on the table, pushing with our fingers and with one chopstick).

Finally, we tried to lift both bottles with a chopstick:

BOTTLE A

             

Alex couldn't lift bottle A

 

BOTTLE B

             

 Rim could lift bottle B

COMPARING BOTH BOTTLES, A & B

             

OUR MATERIALS

We discovered that FRICTION is a special type of contact force. Friction is produced when the surfaces of two objects rub against each other.
