Mechanics and its different branches in physics

What is mechanics in physics? The branch of science that deals with the study of motion of body,its causes and effects. The importance of mechanics It is the oldest of the physical sciences,is the study of the motion of objects.The calculation of the path of a baseball or of a space probe sent to Mars is among its problems,as is ...

types of vectors in physics with images

A vector is represented graphically by a directed line segment or an arrow head line segment.The length of line,according to the scale chosen ,represents the magnitude of the vector while arrow head indicates the direction.Also they follow triangle law of addition.For example force,acceleration,torque,momentum ,angular momentum etc.To represent a vector we need: A suitable scale Reference axis x,y & z axis ...

Pascal’s principle (law): formula,applications & examples in real life

Archimedes principle Pascal law What is Pascal’s Law and how do we use it? An external force applied on the surface of a liquid increases the liquid pressure at the surface of the liquid. This increase in liquid pressure in transmitted equally in all directions and to the walls of the container in which it is filled. This result is ...

Instantaneous velocity:Formula examples and problems

Instantaneous velocity “If a body covers small displacement in in small interval of time than its velocity will be instantaneous velocity such that Δt is equal to zero.”Where Δt is the small interval of time.Average velocity does not tell us about the motion between two points on the path.The path may be straight or curved and the motion may be steady or ...

What is difference between angular and tangential velocity?

The difference between angular velocity and tangential velocity is that “The angular displacement covered by a body in unit time is called angular velocity and tangential velocity is the velocity, which is tangent to the circular path.” Now! We learn in detail about these quantities in an easy way.Keep reading…. Angular velocity “Time rate of change of angular displacement is known ...

Relation between escape velocity and orbital velocity formula

What is  Escape velocity? “The velocity required by a body to escape from the earth’s gravitational field.”It is our daily life experience that an object projected upward comes back to the ground after rising to a certain height. This is due to the force of gravity acting downward. With increased initial velocity, the object rises to the greater height before ...

law of conservation of momentum formula & examples in real life

Guess now! Why the passengers in the bus move forward when the bus stops quickly? What happens when two bodies strike with each other? Why gun recoils back after firing? Do  you want to learn this types of questions then? Let start: Law of conservation of momentum definition According to this law:”The momentum of an isolated system of two or ...

Difference between stable unstable and neutral equilibrium with examples

Types  of equilibrium in physics There are three states or types  of equilibrium in physics Stable equilibrium Unstable equilibrium Neutral equilibrium Stable equilibrium “A body is said to be in stable equilibrium if after a slight tilt it returns to its previous position.” Consider a book lying on the table.Tilt the book slightly about its one edge by lifting it ...

Newton’s third law of motion examples in daily life

Newton’s first law of motion Newton’s second law of motion Newton’s 3rd  law of motion explains the quantitatively that how forces affect motion.But question is that where these forces come from?We noticed during observations that a force on any object always exerted by another object. For examples: A horse pulls a cart ,a person walks on the ground, hammer pushes ...

Newton’s second law definition and formula

  According to Newton’s first law of motion “if no net force is acting on a body at rest, then the body remains at rest, or if the body is moving will continue to move.” But! What will happen if the net force is act on a body? Newton perceived that velocity of a body increased or decreased by applying ...
