Types of forces

1. Applied Force
1.1. An applied force is a force that is applied to an object by a person or another object. If a person is pushing a desk across the room, then there is an applied force acting upon the object. The applied force is the force exerted on the desk by the person.
2. Air resistance force
2.1. Air resistance is the force acting on an object that is moving through air flowing in the opposite direction. The air “resists” the object's movement, slowing it down by friction that is created as the object collides with air molecules.
3. Tension Force
3.1. Tension is defined as the force transmitted through a rope, string or wire when pulled by forces acting from opposite sides. The tension force is directed over the length of the wire and pulls energy equally on the bodies at the ends.
4. Contact Force
4.1. An object at rest on a surface exerts a force on the surface. The reaction force acts at right angles to the surface and is known as the normal contact force. For example, a book on a table.
5. Electric Force
5.1. Electric force is the force of attraction or repulsion between two charged objects. It's a type of non-contact force that can act on objects without touching them.
6. Electromagnetism
6.1. The electromagnetic force is a type of physical interaction that occurs between electrically charged particles. It acts between charged particles and is the combination of all magnetic and electrical forces. The electromagnetic force can be attractive or repulsive.
7. Nuclear Force
7.1. The nuclear force (or nucleon–nucleon interaction, residual strong force, or, historically, strong nuclear force) is a force that acts between hadrons, most commonly observed between protons and neutrons of atoms. Neutrons and protons, both nucleons, are affected by the nuclear force almost identically.
8. Gravity Force
8.1. an invisible force that pulls objects toward each other. Earth's gravity is what keeps you on the ground and what makes things fall. An animation of gravity at work. Albert Einstein described gravity as a curve in space that wraps around an object—such as a star or a planet.
9. Muscular Force
9.1. Muscular force is the force that muscles apply to an object when they contract or relax. It's a type of contact force that occurs when two surfaces touch.
10. Gravitational Force
10.1. 1) Gravitational Force. The force that pulls all objects towards the Earth. Gravity is the gravitational force.The weight of an object is the amount of gravitational force acting on it. The greater the mass of an object, the greater the gravitational force acting on it, hence the greater its weight.
11. Frictional Force
11.1. 2) Frictional Force (friction). Friction is a force that opposes motion (acts in the opposite direction) when two surfaces are rubbed together or are in contact with each other. The amount of friction produced depends on the types of surfaces in contact. The rougher the surfaces, the more friction between the two surfaces. Air resistance and water resistance refer to friction in air and water respectively. Energy is needed to overcome these frictional forces and this reduces the maximum speed we can reach. Friction causes a moving object to slow down and stop.
12. Elastic Spring Force
12.1. 3) Elastic Spring Force. The materials that can change their shape and length when a force is applied and return to the original shape when the force is removed are said to be elastic.
13. Magnetic Force
13.1. 4) Magnetic Force. Magnetic forces are pushing and pulling force exerted which can act at a distance. A magnet can exert a force of attraction (pull) or repulsion (push) on another magnet.
14. Normal Force
14.1. Normal force is a contact force applied by a surface on an object. It can be calculated through the application of Newton's Second Law, and its direction is opposite to the weight of one of its components. The normal force always has a 90-degree angle with the surface that applies it.
15. Force
15.1. The push or pull on an object with mass causes it to change its velocity. Force is an external agent capable of changing a body's state of rest or motion. It has a magnitude and a direction.
16. Electrostatic Force
16.1. The electrostatic force is an attractive as well as repulsive force caused by the electric charge particles.
17. Weak Force
17.1. In an atomic nucleus, protons and neutrons are held together by the strong force. In contrast, the weak force doesn't hold things together or push them apart. Instead, it changes the “flavor” of a quark so that it changes from an up quark to a down quark or vice versa.
18. Push and Pull Force
18.1. A "push" force is when you apply force to move an object away from you, while a "pull" force is when you apply force to move an object towards you; both are considered types of forces that can cause an object to move or change direction, with the key difference being the direction of the applied force relative to the person applying it.
