What are the 7 named Forces?

Question

I have, yes Science homework, I mean to say, my science teacher TOLD us the 7 forces but we all forgot them... As quick as possible please!
Thank you xxx

By the way there are SEVEN cos my science teacher said so

By the way, I'm in yr7 not 11!!

Actually my teacher IS crazy

Answer 1

1.Gravitational Force
2. Frictional force
3. Electrostatic Force
4. Centripetal Force
5. Centrifugal Force
6. Magnetic Force
7. I cant remember it (its been 5 years now..)

Answer 2

Ah took me a while to work that out... OK here we go

A Static Load : A person holding a stack of books on his back but he is not moving. The force downwards is STATIC.

A Dynamic Load : If he is carrying a weight of books but then starts walking. The force is moving or DYNAMIC.

Internal Resistance : An air filled tyre is under great pressure. The air pressure inside it pushes back against the weight of a car and passengers

Tension : If two people pull on a rope, this stretching puts the rope in tension.

Compression : A weight lifter's body is compressed by the weights he is holding above his head.

Shear Force : eg simple scissors. The two handles put force in different directions on the pin that holds the two parts together. The force applied to the pin is called shear force.

And the the 7th is....Torsion
e.g. A plastic ruler twisted between both hands. The ruler is said to be in a state of torsion.

That's the right answers, just hope it's to the right question!

Answer 3

There are only four forces: Gravity, Electromagnetism, Strong, and Weak. All other forces are combinations of these. In the everyday world where there aren't any nuclear reactions going on, there is only Gravity and Electromagnetism. All forces in the everyday world that aren't gravity are electromagnetic.

If your science teacher thinks there are seven fundamental forces, s/he probably needs to have some remedial training.

Answer 4

There are only 4 forces and they have been given by just about everyone who has replied.

Tell your teacher what they are and if he claims otherwise direct him to the nearest mental health facility (or simply have him do a little research on the internet).

I weep for the future of math and science in America.

Answer 5

A force by definition is a force.
They come in large ,medium and economy sizes.
And any name can be given them An example would be the force of the wind,the force of an atomic blast, the force of a neutron spliting the nucleus of an atom, The force of electro static gravity holding two protons together,the force of an earth quake ,the force of a mosquito flying into a windshield, the force of a twister tornado,the gravity force holding the human body into a shape, the force between two magnetic masses , the force between two electrostatic charged bodies ,the force between two Neutrons,The force due to the curvature of space and time,And the Universal force etc...

Basically in the world of physics Force is a phenomenon which occurs between two interacting masses.Forces are always born in pairs equal in magnetude but opposite in direction. Force is measured in Newtons whose dimension is=kg m/sec^2.

Answer 6

Yes, Trekky06 is correct.

As far as I know there are only four forces and he named them all (the weak, the strong, gravity, and electromagnetism).

Plus there are only four laws of thermodynamics too.

Answer 7

As far as I know, there are only four.
- Gravity
- Electromagnetism
- Weak Nuclear
- Strong Nuclear

Answer 8

typing SEVEN in capital letters does not make 3 more appear

maybe everyone is missing the context of your class, or maybe you are unable to listen for the second time today :)

Answer 9

Abe itna easy question nhi aata????vaise toh mujhe bhi nhi aata........
