Forces

Forces are a fundamental concept in physics, describing the interaction between two objects that results in a change in motion. They can be categorized into two main types: contact forces and non-contact forces.

Contact Forces[edit | edit source]

Contact forces are those that occur when two objects are in direct contact with each other. Examples of contact forces include friction, tension, normal force, and air resistance.

Friction[edit | edit source]

Friction is a force that opposes the motion of an object. It is caused by the interaction between the surfaces of two objects in contact.

Tension[edit | edit source]

Tension is a force that is transmitted through a string, rope, cable or similar object when it is pulled tight by forces acting from opposite ends.

Normal Force[edit | edit source]

The normal force is the force exerted by a surface that supports the weight of an object resting on it.

Air Resistance[edit | edit source]

Air resistance is a type of frictional force that acts against the motion of an object moving through air.

Non-Contact Forces[edit | edit source]

Non-contact forces are those that can act at a distance, without the need for physical contact. Examples of non-contact forces include gravity, electromagnetic forces, and nuclear forces.

Gravity[edit | edit source]

Gravity is the force of attraction between all masses in the universe.

Electromagnetic Forces[edit | edit source]

Electromagnetic forces are forces that occur between charged particles.

Nuclear Forces[edit | edit source]

Nuclear forces are forces that act between particles in the nucleus of an atom.
