Explain the different types of forces.
Answers
Answer:
Basically, there are two main types of forces, contact forces, and non-contact forces. Gravitational forces, electric forces, magnetic forces, nuclear forces, frictional forces are some examples of force. ps make me brainlist
Good question
Explanation:
Types of forces with examples
Basically, forces are of two types: Contact forces & Non-contact forces or At a distance forces
● Contact forces:- Those forces which represent the result of physical contact between two objects, where one of the objects exerts force on the other.
○ 6 Types of contact forces
- Applied force:-Force due to the action of muscles is called applied force.
- Normal force:-It is a contact interaction force between surfaces. It always acts perpendicular to the surfaces and out of the surface. It comes from the microscopic deformation of molecules modeling a system of springs.
- Frictional force:-It comes from interactions with a surface as an object moves or tries to move relative to the surface.
- Tension force:-An applied force where the force is applied through a string, cable, rope, etc..
Note that a tension force can only pull, it cannot push. We usually assume the tension in a cable is the same everywhere in the cable.
- Air resistance force:-The force that acts in a direction opposite motion through a gas is called air resistance force. It comes from cumulative interaction with air molecules. It increases as the velocity through the gas increases. It also increases as the area normal to the direction of motion increases.
- Spring force:-The force that acts in a direction opposite motion through a gas is called air resistance force. It comes from cumulative interaction with air molecules. It increases as the velocity through the gas increases. It also increases as the area normal to the direction of motion increases.Spring force comes from the displacement of molecules. It is always opposite the displacement of spring.

● Noncontact forces:-Those forces which do not involve physical contact between the two objects but act through the space between the two.
○ 4 Types of Noncontact forces
- Gravitational force:-Attractive force exerting between two objects is called gravitational force. It originates with the presence of matter.
- Electromagnetic force:-The electromagnetic force which includes basic electric and magnetic interactions and is responsible for the binding of atoms and the structure of solids.
- Weak nuclear force:-The weak nuclear force which causes certain radioactive decay processes and certain reactions among the most fundamental particles.
- Strong nuclear force:-The strong force which operates among the fundamental particles and is responsible for binding the nucleus together.
