Definition of Kinetic Energy:
Kinetic energy is the energy possessed by an object due to its motion. If an object is moving, then it has kinetic energy. The amount of kinetic energy depends on mass and speed.
Definition of Potential Energy:
Potential energy is the energy stored in an object due to its position. The most common type of potential energy - gravitational potential energy - is the energy stored in an object due to its vertical position relative to the ground or some zero level. The amount of gravitational potential energy depends upon mass and vertical height.
Definition of Work and Non-conservative Work:
Work is done when a force is acting upon an object to cause (or to hinder) a displacement. Work is considered to be non-conservative work if it is done by forces such as tension, friction, applied, normal, and air resistance.
