Forces and its types
What is Force?
Without force, nothing can be moved, stopped or change the direction. It is a quantitative interaction between two physical bodies, between an object and its environment. There are various types of forces in nature.
If an object is in its motion state than its current state will be either static or motion. Its position will only be changed if it is pushed or pulled. The external push or pull applied on the object changes its current state of motion is known as Force. This force can be of different types. They are stated below.
Different Types Of Forces
Force is a physical cause that can change the state of motion of any object or the dimensions. Different types of Forces are listed below-
Contact Forces
The contact forces are the forces which occurs when we apply some effort on an object.
Following is the classification of contact force:
** Spring Force |
** Applied Force |
** Air Resistance Force |
** Normal Force |
** Tension Force |
** Frictional Force |
Non-Contact forces
The non-contact forces are the forces which occurs from a distance.
Following is the classification of non-contact forces:
**. Electromagnetic Force |
**. Gravitational Force |
**. Nuclear Force |
Spring Force
This force works opposite to the displacement of molecules. Like in a spring or elastic rubber band etc.
Applied Force
The force which is applied by our muscles is called applied force is also called muscular force. For example, pushing a box or kicking a ball etc.
Air Resistance Force
The force exerted by a gas acting upon a body on the opposite direction is called air resistance force. The examples are the forces experienced by a skydiver or a downhill skier etc.
Normal Force
It is referred to the force which acts when two surfaces are in contact. This force is perpendicular to the surface and acts in the direction out of the surface. For example, a box on top of a table.
Tension Force
This type of force is experienced by a rope or a string which holds an object.
The tension force is always a pull not a push. The tension force is same throughout the cable.
For example, a ball hanging with the help of a string.
Frictional Force
Frictional force acts when the objects on a surface is trying to moves relative to surface. For example, when a box is slid on a table.
Electromagnetic Force
These are the magnetic and electric interactions between atoms and molecules which helps in binding and defining the structure of solids.
For example, in a magnet, poles attract each other.
Gravitational Force
It is defined as the force acting between objects due to presence of matter. For example, Earth’s gravity acting upon objects and is given as:
Nuclear Force
The force responsible for the bonding of nucleus is known as nuclear force. For example, forces resulting in radioactive decay.
Balanced Force
When two forces are in opposite direction and possess equal magnitude then these forces called are a balance force.
Unbalanced Force
The unbalanced force can be defined as ” when two forces acting on a body are of unequal size.
