How many different types of forces are there?

Answer 1

If you are referring to the fundamental forces of nature; there are four, being:

-Electromagnetism; this is the force responsible for all things involving magnets and electricity.

-Gravity; this is the force that causes objects with mass (more correctly energy) to attract each other. It causes things to fall down and is probably the force most people are most familiar with.

The last two forces are not generally known because their influences usually are only felt in the world of small things such as atoms, and their influences are only rarely seen in the every day world.

-Weak nuclear force; this force governs certain interactions of sub-atomic particles and in particular it is responsible for radioactive decay.

-Strong nuclear force; this force works on only a few types of particles; particles which have a color charge. It is, for example, responsible for binding the protons and neutrons together inside an atomic nucleus. Without this force the nucleus would be pushed apart because the protons repel each other electromagnetically.

Answer 2

Colinear Forces: System of forces acting on a single line

Coplanar Forces: System of forces acting on the same plane

• Coplanar Concurrent Forces: System of forces acting on the same plane and passing through the same point
• Coplanar Non-Concurrent Forces: System of forces acting on the same plane and passing through different points
• Coplanar Non-Concurrent Parallel Forces : System of forces acting on the same plane, passing through different points and are parallel to each other
• Coplanar Non-Concurrent General Forces: System of forces acting on the same plane, passing through different points and are not parallel to each other

Non-Coplanar Forces: System of forces acting on different planes

• Non-Coplanar Concurrent Forces : System of forces acting on different planes and passing through the same point
• Non-Coplanar Non-Concurrent Forces : System of forces acting on different planes and passing through different points
• Non-Coplanar Non-Concurrent Parallel Forces: System of forces acting on different planes, passing through different points and are parallel to each other
• Non-Coplanar Non-Concurrent General Forces Non-Concurrent Parallel Forces: System of forces acting on different planes, passing through different points and are not parallel to each other
