Impulse momentum equation with examples and applications in real life

What is momentum? “Momentum of a body is the quantity of motion it possesses due to its mass and velocity.”We are aware of the fact that moving object possesses a quality by virtue of which it exerts a force on anything that tries to stop it.The faster the object is travelling ,the harder is to stop it.Similarly,if two objects move ...

Different types of forces and their examples

What is Force? “A force moves or tends to move,stops or tends to stop the motion of object.The force can also change the direction of motion of an object.”It can also change the shape or size of a body on which it acts. In classical physics real forces are defined by a set of axioms,Newton’s laws of motion,with reference to ...

Projectile motion:definition,types,equations with examples

What is a projectile? A body thrown at a some angle θ above or below the horizontal such that (0 < θ < π/2) and moves freely under the action of gravity is called projectile. What is projectile motion? “Projectile motion is two dimensional motion under constant acceleration.”or When a body is thrown vertically upward then it follows a curved path such a motion of ...

kinematic equations of motion derivation with problems

5 kinematic equations

Kinematic equations Kinematics is the branch of mechanics dealing with the motion of bodies without reference to mass or force.There are three basic equations of motion for bodies moving with uniform acceleration.These equations relate initial velocity,final velocity,acceleration,time and distance covered by a moving body.To simplify the derivation of these equations,we assume that the motion is along a straight line.Hence,we consider ...

acceleration:definition,formula,examples and problems

What is acceleration in physics? “Acceleration is defined as the rate of change of velocity of a body.”In many cases the velocity of a body changes  due to a change either in its magnitude or direction or both.The change in the velocity of a body causes acceleration in it.If an object is moving at a constant speed but changes its ...

Average velocity formula with examples

Velocity is defined as:”The rate of displacement of a body is called its velocity.”The velocity tells us not only the speed of a body but also the direction along which the body is moving.Velocity of a body is a vector quantity.It is equal to the displacement of a body in unit time.And is represented as:           ...

Speed:average,uniform and instantaneous speed with examples

Speed Velocity Acceleration What is speed in physics? “The distance covered by an object in unit time is called its speed”.In other words ,the rate at which object is moving is called speed.Unit time may be a second,an hour,a day or a year.It tells us how fast or slow an object is moving .Its formula is given as: Here S ...

what are the different types of sources of energy?

  “Energy is the ability of a body to do work.”It is  present everywhere in sunlight,water,wind,plants,animals etc..It is required for walking, reading and playing.Energy does makes things for us like makes toast,plays music etc..A good source of energy would be the one which would: Do a large amount of work per unit volume or mass. Be easily be accessible Be ...
