what is force and what are the types of force
Answers
Force is strength or energy applied towards any object for physical action or any movement. A force is a push or pull resulting due to the interaction between two objects. Force is external and results only when there is interaction between objects.
Different types of forces
Force can be classified into two broad categories
1. Contact forces
These are those types of forces when two objects interact with each other; they have a physical contact with each other. Types of contact forces are: Frictional force; Tension force; Normal Force; Air Resistance Force, Applied Force, Spring Force.
- I. Frictional force
- II. Tension force
- III. Normal force
- IV. Air Resistance force
- V. Applied force
- VI. Spring force
2. Action at a distance forces
These types of forces happen when two interactive objects are not in physical contact with each other; yet they are able to push or pull. Types of Action at a distance forces are: Gravitational force, Electrical force and Magnetic forces.
- I. Gravitational force
- II. Electrical force
- III. Magnetic force
Force is that cause which either changes or tends to change the shape, size, dimensions, state of rest, state of motion etc. of an object over which it acts.The SI unit of force is newton, denoted by N . The forces are mainly divided on the basis of when it acts. The types of forces are given below : -
1. Contact Forces
The forces that are applicable only when the objects under consideration are in actual physical contact with each other are called contact forces. Examples: Frictional Force, Muscular Force, Force of Tension, etc.
2. Non-contact Forces
The forces that are applicable even if the objects under consideration are not in actual physical contact are named non-contact forces. Examples: Gravitational Force, Electrostatic Force, Magnetic Force, etc.
