What are the forces acting between two masses?

In summary, the forces acting between two masses are dependent on the mass and distance between them. The magnetic field is generated by moving a charged particle, while the electric field is generated by a charged particle's presence. The main difference between magnetic and electric fields is that the magnetic force on a charged particle is dependent on its speed and direction, while the electric force is not.

hi abi.ayan! :smile:

too complicated!
can anyone explain how magnetic field is generated

the only way of making a magnetic field is by moving a charged particle

(usually an electron along a wire, or an electron in a tiny circle in a material)
and what are the differences between magnetic and electric field?

they both only act on charged particles, by a force

the electric force on a charged particle does not depend on what the particle is doing

the magnetic force on a charged particle depends on the speed and direction of the particle (and is always perpendicular to the direction of the particle … for example, a loop of current in a magnetic field can be moved sideways to the loop, which is how a magnet attracts iron)

FAQ: What are the forces acting between two masses?

What are the forces acting between two masses?

The forces acting between two masses are gravity, electromagnetic force, strong nuclear force, weak nuclear force, and friction.

What is gravity?

Gravity is the force of attraction between two objects with mass. It is responsible for keeping planets in orbit around the sun and objects on Earth from floating away.

What is electromagnetic force?

Electromagnetic force is the force between charged particles. It is responsible for interactions between atoms and molecules, as well as electricity and magnetism.

What is strong nuclear force?

Strong nuclear force is the force that holds the nucleus of an atom together. It is the strongest force among all the fundamental forces and is responsible for nuclear reactions.

What is weak nuclear force?

Weak nuclear force is responsible for radioactive decay and plays a role in certain types of nuclear reactions. It is much weaker than the other fundamental forces.
