TYPES OF FORCES

Hey! I am not able to remember the types of forces we studied today. Can you help me please?

Yes! Why not?!

Thank You!

So, let me start with FORCE. Force is a Pull or Push that affects an object in some way.

Okay! I got it.

For holding the books, my muscles are being used too. So, it can be also called MUSCULAR FORCE.

See, as you will hold the burger, there is a physical contact between the burger and your hand, so it is called CONTACT FORCE.

This is exactly what I asked ma'am today.

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 physical contact.



See, now the books fell down. So, there is no physical contact between the books and my hand, It is called NON - CONTACT FORCE.

Oh! Now I am able to relate these with my Textbook.

I tripped over the books. Ooouuch !! It hurts..

It happened because of FRICTIONAL FORCE. It is the force that opposes motion when two or more objects are in contact move in respect to each other.

I will orally explain the other forces left as I don't have the materials to show as example.

First is the MECHANICAL FORCE, the force exerted by machines.Eg - Engine of a Car, Closing and Opening of door.

Other is MAGNETIC FORCE, the force exerted by a Magnet or Magnetic substances.Eg - Magnet attracts Iron

Thank you so much! I understood FORCE and TYPES OF FORCE properly by the examples you gave me today.
