## What is the Conservative force?

Know in one minute about the Conservative force When work done on a body in a closed loop is zero or work done doesn’t depend on the path, then the applied force is a conservative force. Work done by the body will be conserved. Gravitational force, spring force, coulomb force, and magnetic force are examples. […]

## What is relative velocity?

Know in one minute about Relative velocity Relative velocity is the velocity of an object concerning other objects. It affects many activities performed by humans, such as crossing a boat, swimming, police catching a thief, etc. Normal velocity is also the relative velocity with respect to the ground.   Introduction Relative velocity is a phenomenon

## Moment of force: Definition and discussion

Know in one minute about the Moment of force (Torque) Moment of force is the turning effect of a force of a rotating body. Force is not only a factor in the movement of a body, but it plays an important role in the rotation of the body. The moment of force can be defined

## Number of tetrahedral voids in bcc

Introduction The total number of tetrahedral voids in bcc is 4. Let us see how to find out In a body centered cubic(bcc) structure, there are a total of 2 atoms present in a cubic lattice.  The number of tetrahedral voids in any lattice is 2N, where N represents the number of atoms.  So, in

## One dimensional motion:definition and examples

Introduction The motion refers to the change in an object’s position over time and is defined by its velocity, distance, acceleration, displacement, speed, and time. The motion of an object is always measured with respect to some frame of reference. Motion can occur in one, two, or three dimensions, where one-dimensional motion is linear, two

## Work Energy Theorem

Introduction The work-energy theorem states that the net work done by the net forces acting on a  particle is equal to the change in the kinetic energy of the particle. After the net force is removed the particle’s total energy is changed due to the work that was done. The work-energy theorem is not independent

## Difference between elastic and inelastic collision

Introduction The difference between elastic and inelastic collision mainly depends upon the kinetic energy. In simple words, in an elastic collision, no loss of kinetic energy occurs whereas, in an inelastic collision, the loss of kinetic energy occurs. When two objects come near each other, a force affects them for a short period, causing a

## Instantaneous Velocity: Definition and examples

Know in one minute about Instantaneous Velocity Velocity is a term that describes how fast something is covering a distance in a particular direction. The measurement of velocity for large differences in time is called average velocity. It is the measurement of time when the difference becomes closer to zero. The formula is It is

## Laws of conservation of momentum

Introduction Sir Isaac Newton discovered the law of conservation of momentum while formulating the laws of motion. The law of conservation of momentum is a direct consequence of Newton’s third law of motion. When two or more bodies act upon one another then in the absence of an external force, the total momentum of all

## Define uniform circular motion with examples

Know in one minute about Uniform circular motion When a particle or object moves along a curved or circular path, the motion of that particle or object is called circular motion. Motion while turning a vehicle on a curved road is circular motion. There are two types of circular motion, Nonuniform circular motion Uniform circular
