what is the force?
Force is the factor acting on an object due to which the physical state of that object changes. In simple language, if we understand the definition of force, force is the interaction on an object due to which the initial state of the object changes. Let us know in detail what is the force and how to force conversion happens. The dimension of force is [LMT^-2 ] and force is a vector quantity.

F = ma.
where F= force, m=mass and a= acceleration.
1N = 1kg 1ms-2
1N = Ikgms-2
Other units of force:- dyne, pound-force, poundal, kip, kilopond.
Example:- we applied the force on door to shut it or open it.
Which law of force meets the definition of Newton?
We get the definition of force from Newton's first law of motion, according to Newton's first law of motion, "If an object is in the kinetic state or stationary state, it will remain in that state until an external force is applied to that object. "If an object is going in some direction, it can be stopped by applying force on it and its speed can be increased further by applying force. That is, force is required to change the physical state of an object.
What is the unit of force?
A unit is required to measure any object. Similarly, some units have been made to measure the force,
What is the CGS unit of force?
CGS is also a unit for measuring force. In the CGS method, the unit of force is dyne. In the CGS unit, the unit of dyne is represented by d. Where 1 newton = 10 ^ 5 is dine.
What is the Force effect?
The force exerted on an object due to which the shape or position of that object changes is called the effect of force. Due to the effect of force, the object starts moving.
Unit of force conversion
Here some major forms of change are being given to the unit of force. The unit of force, Newton, is represented by (N).
1 kilonuton (kN) = 1000 newton (N)
1 gram-force (gf) = 0.00980665 newton (N)
1 kg-force (kgf) = 9.80665 newton (N)
1 ton force (metric) (tf) = 9806.65 newton (N)
1 exuton (EN) = 1.0E + 18 newton (N)
1 petanuton (PT) = 1.0 e + 15 newton (N).
Type of Force
There are mainly two types of force: one is contact force and another is non- contact force. These two forces are divided into several types, a different force acts at a different place. Let us know these types of force in detail.
contact force
Any force that requires contact is called contact force. Contact forces are ubiquitous. For example, muscle force andfriction force also have contact force. Without contact force, muscle force or friction force cannot work. OR
"Interaction between objects which is touch to the object".
Example - pushing the car and breaking the cycle etc.
Non-contact force
The Non-contact force is opposite to the contact force. Non-contact force is a force that acts on an object without physically coming into contact with it.OR
"Attractor repel, even from a distance".
Example - The most familiar example of non-contact force is gravity which controls weight
Gravitational force
The force of attraction on the mass of an object by a body is called gravitational force. The force of attraction between two mass objects due to which they try to pull each other is called the force of gravity. Gravity found on Earth gives weight to all physical objects. Every other object in the entire universe exerts a gravitational force.
Example - Earth moves around Sun due to gravitational force and Moon also revolves around Earth due to gravitational force.
Frictional force
The force between two layers of any object that acts opposite to the motion of those objects is called friction force. The frictional force is applied on the surface of objects and prevents them from slipping.
Example - Braking of a bicycle is the force of friction. Due to the force of friction, we walk on the road. The friction forceon the ball and round objects is less.
Magnetic force
The force exerted by a magnet on a magnetized metal or other magnets that attracts and draws it is called the magnetic force of that force. Its other types are permanent magnets, temporary magnets, and electromagnets.
Example - Pasting an iron object with a magnet.
Muscular force
The force exerted using the muscles of our body and parts of the body such as hands or feet, is called muscular force.
Example - Muscle force is also used in lifting the bucket, pushing the car and in the gym, etc. That is, muscle force is used in all the work that we do.
Electromagnetic force
The force acting between all charged particles of electric force (whether they are moving or not) is called electromagnetic force. When a magnetic force acts between moving charged particles, it is called electromagnetism.
Example - The best example of the electromagnetic force is light. All light waves in the electromagnetic field from gamma rays.
Buoyancy force
The force acting inside a fluid, which acts when the object is moved upwards, is called buoyancy force. The buoyancy force is an upward force emitted by a fluid that opposes the weight of a submerged object.
Example - When lifting an object on earth or out of the water, it makes you feel heavy but the same object becomes lighter in water and it becomes easier to lift due to buoyancy force.
Lorenz Force
The Lawrance force is a combination of electric and magnetic forces at a point charge due to electromagnetic fields.
Suppressive force
The force exerted between molecules similar to any substance is called cohesive force.
Adhesive force
The force exerted between dissimilar or different molecules of any substance is called cohesive force.
Balanced force
If the force applied on both directions of an object has the same value, its resultant force is zero, then there is a balanced force. This force is on the object in opposite directions and in equal size.
Unbalanced force
Unbalanced force is the opposite of a balanced force. If the value of the force applied on both directions of an object varies, then there is a balanced force. The motion and direction of the object changes due to the unbalanced force.
