Elastic collision in One Dimension

The elastic collision in which the colliding particles moving along the same straight line path before and after the collision is called one-dimensional elastic collision. Consider two bodies A and...

Conservative and Non-conservative Forces

Conservative ForcesA force is said to be conservative if work done by the force or against the force on moving a body depends only on initial and final position of the body and is independent on th...

Principle of Conservation of Energy

Principle of conservation of energy states that, “energy can neither be created nor be destroyed but can be converted from one form to another form.” Therefore, the total energy of the universe is ...

Potential Energy

The energy possessed by a virtue of its position or molecular arrangement(configuration) is called potential energy.The potential energy is of the following three types:Gravitational potential ener...

Work-Energy Theorem

Work-Energy theorem states that “the work done on a body by a resultant force is equal to the change in kinetic energy of the body.” Suppose a body having mass ‘m’ is moving initially with velocity...

Kinetic Energy

The energy possessed by a body by virtue of it’s motion is called kinetic energy. A body moving with higher speed will possess more kinetic energy than body moving with lower speed. To derive the e...

Work Done by a Constant Force

So, we have discussed the introduction to work and energy in the previous section.Now let's discuss about work done by a constant force.Work is defined as the product of the magnitude of the displa...

An Introduction to Work and Energy

WorkScientifically,Work is said to be done by a force when the force produces a displacement in the body on which it acts in any direction except the direction perpendicular to the direction of th...
