See now the books fell down. So there is no physical contact between the books and my hand, it is called Non-Contact force.
Yes Mom, I am able to relate these with my textbook.
Lexi, I am able to stand because the gravity is pulling me towards the ground.So, it can be also called gravitational force . The objects need not always be in the physical contact.

Lexi, do you feel your hair being pull by the TV screen?
It's ok. Darling. It happen ed because of frictional force. it is the force that opposes motion when two or more objects are in contact move in respect each other.
Mom, I tripped over the books. Ooouuch!!It Hurts..
Yes Mom, I do
It is because of electrostatic force. Before you came into the room, I was watching TV , So , the TV is changed body and your hair is uncharged hence. it was attracting your hair
Is it still hurting?
