## What is Force?

In physics, force is a fundamental concept that describes the influence or push-pull effect that one object exerts on another. It is a vector quantity, which means it has both magnitude (strength or size) and direction. Force is measured in units called newtons (N) in the International System of Units (SI).

Key characteristics of force include:

1. Magnitude: This refers to the strength or intensity of the force. It is expressed in newtons (N), with 1 newton being defined as the force required to accelerate a 1-kilogram mass by 1 meter per second squared (1 N = 1 kg·m/s²).
2. Direction: Force is a vector quantity, which means it has a specific direction in space. In many cases, forces are represented by arrows indicating their direction.
3. Point of Application: A force is applied at a specific point on an object or between two objects.
4. Interaction: Forces result from the interaction between objects. They can be caused by direct contact (contact forces) or act at a distance (long-range forces), such as gravitational or electromagnetic forces.
5. Net Force: When multiple forces act on an object, the net force is the vector sum of all these forces. It determines the object’s motion according to Newton’s second law.
6. Units: The SI unit of force is the newton (N), but other units like dynes and pounds are used in some contexts.
7. Types of Forces: Forces come in various types, including gravitational force, electromagnetic force, nuclear forces, tension, friction, normal force, and applied force, among others.

## All Formulae Related to Force

1. Newton’s Second Law:
• F = ma
• Force (F) is equal to the mass (m) of an object times its acceleration (a). This law describes the relationship between force, mass, and acceleration.
2. Weight:
• F = mg
• The weight (F) of an object is equal to its mass (m) times the acceleration due to gravity (g). This formula is used to calculate the force of gravity acting on an object on Earth’s surface.
3. Gravitational Force:
• F = G * (m1 * m2) / r^2
• The gravitational force (F) between two objects with masses m1 and m2 separated by a distance r is given by the formula, where G is the gravitational constant.
4. Tension in a String or Cable:
• T = F + ma
• The tension (T) in a string or cable is the force required to accelerate an object of mass m. It is equal to the sum of the force applied (F) and the force needed for acceleration (ma).
5. Frictional Force:
• F_friction = μ * N
• The frictional force (F_friction) is proportional to the normal force (N) and is determined by the coefficient of friction (μ) between two surfaces in contact.
6. Spring Force (Hooke’s Law):
• F_spring = -k * x
• The force exerted by a spring is directly proportional to the displacement (x) from its equilibrium position and is determined by the spring constant (k). The negative sign indicates that the force acts in the opposite direction of the displacement.
7. Pressure Force:
• F_pressure = P * A
• The force exerted on a surface due to fluid pressure (F_pressure) is equal to the pressure (P) times the surface area (A) over which the pressure acts.
8. Electrostatic Force (Coulomb’s Law):
• F_electric = k * (|q1 * q2|) / r^2
• The electrostatic force (F_electric) between two charged particles with charges q1 and q2 separated by a distance r is given by the formula, where k is the electrostatic constant.
9. Magnetic Force (Lorentz Force):
• F_magnetic = q * (v x B)
• The magnetic force (F_magnetic) on a charged particle with charge q moving at velocity v in a magnetic field B is given by this formula, where “x” represents the vector cross product.
10. Centripetal Force:
• F_centripetal = (mv^2) / r
• The centripetal force (F_centripetal) required to keep an object of mass m moving in a circular path with a radius r at a constant speed v is given by this formula.
