## Types of forces in physics with examples

Force is the external agent which produces motion or tends to produce motion or it stops motion or tends to stop motion. Basically, there are two types of forces, contact forces, and non-contact forces. Gravitational force, electric force, magnetic force, nuclear force, frictional force are some examples of force. Now! We learn in detail about kinds of force…… Here’s the ...

## types of vectors in physics with images

In this topic we will stay about different types of vectors like unit, free , null vector, like , unlike, coplanar, position, initial, proper, negative and equal vectors.   Further, we will learn with examples to get better understandings. Suggested video: Types of vectors In general vectors may be divided into three  types. Proper vectors Axial vectors Inertial or pseudo vectors Proper vectors Displacement ,force,momentum etc ...

## dot product and cross product of vectors

Dot product and cross product are two types of vector product.The basic difference between dot product and scalar product is that dot product always gives scalar quantity while cross product always vector quantity.Dot product is always used to calculate angle between two vectors. What is dot product of two vectors? When two vectors are multiplied with each other and answer ...

## Newton’s three laws of motion with examples and applications

Newton’s three laws of motion are the 3 physical laws ,these laws of motion laid the foundation for classical mechanics.These laws explain the relation between forces and the body on which these forces acted upon.Newton’s first law of motion gives the qualitatively definition of force,Newton’s second law of motion gives the quantitative measure of the force,while Newton’s third law of ...

## Scientific notation and significant figures

Scientific notation and significant figures are two important terms in physics.In scientific notation numbers are expressed by some power of ten multiplied by a number between 1 and 10,while significant figures are accurately known digits and first doubtful digit in any measurement.  Scientific notation definition In scientific notation a number is expressed as some power of ten multiplied by a ...

## Newton’s first law of motion examples in our daily life

Newton’s first law of motion examples are given in the list: A book lying on the table remains at rest as long as no net force acts on it. A moving object does not stop moving by itself. A rolling ball on rough surface or ground stops earlier than on smooth surface,because rough surfaces offer more friction than smooth surface.If ...

## Difference between conservative and conservative force with examples

Conservative and non conservative force examples are given in which Gravitational forces,Magnetic force,Electrostatic force,Elastic spring force,Electric force are conservative force examples while frictional force,air resistance force,force of gravity are non conservative force examples. What are conservative forces? Those  forces which allows the opportunity of two way conversion among potential and kinetic energies are said to be conservative forces. Conservative force ...

## Difference between dot product and cross product in tabular form

Vector dot product and cross product are two types of vector product,the basic difference between dot product and scalar product is that in dot product,product of two vectors is equal to scalar quantity while in scalar product,product of two vectors is equal to vector quantity.  dot product Vs cross product   Dot product or scalar product  Cross product or vector ...
