### Inelastic Collision

During a collision between two bodies if there is a loss of kinetic energy, then the collision is said to be an inelastic collision. In...

### Collisions

Collision between two or more particles is the interaction for a short interval of time in which they apply relatively strong forces on each...

### Conservative Forces

Forces are said to be conservative in nature if work done against the forces gets conversed in the body in form of potential energy....

### Power

Power is defined as the time rate at which work is done or energy is transferred. The average power of a force is defined as...

### Conservation of Mechanical Energy

The total mechanical energy of a system is conserved if the forces, doing work on it, are conservative. Suppose that a body undergoes displacement Δx...

### Potential Energy of a spring

Energy possessed by the spring by virtue of compression or expansion against elastic force in the spring is known as elastic potential energy or...

### Potential Energy

Potential energy is the ‘stored energy’ by virtue of the position or configuration of a body. The body left to itself releases this stored...

### Kinetic Energy

If an object of mass m has velocity v, its kinetic energy K is Kinetic energy is a scalar quantity. The kinetic energy of an...

### Work-Energy Theorem

The work-energy theorem states that the change in kinetic energy of a body is the work done by the net force on the body. Kf...

### Work

Work is related to force and the displacement over which it acts. Consider a constant force F acting on an object of mass m....
