Glossary:

"Work and Energy and Harmonic motion"
Work: "The product of the magnitude of an object's displacement and the component of applied force in the direction of displacement." (Nelson, P.731)
Joule: " the SI Unit of Work and Energy". (Nelson, P.728)
Kinetic Energy: " the energy an object has because of it's motion". (Nelson, P.728)
Work Energy Theorem: " the total work done on an object equals the change in the kinetic energy". (Nelson, P.731)
Potential Energy: "the stored energy an object has that can be converted in to another form of energy". (Nelson, P.729)
Mechanical Energy: "the sum o an object kinetic and potential energies".(Nelson, P.728)
Gravitational Potential Energy: " stored energy an object has because of it's position and applied gravitational force".(Nelson, P.728)
Law of Conservation of Energy: "Energy is neither created or destroyed in an isolated system , it can only change form".(Nelson, P.728)
Isolated System: " a system that can not interact or exchange energy with external systems also called the closed system".(Nelson, P.728)
Open System: "a system that can interact with another external system".(Nelson, P.729)
Biochemical Energy: " a type of chemical potential energy stored in the cells and other basic structures of biological organisms".(Nelson, P.725)
Power: " the rate of the work done by a force over time or the rate at witch the energy of an open system change".(Nelson, P.729)
Hooke's Law: "the amount of force exerted by a spring is directed proportional to the displacement of the spring" .(Nelson, P.727)
Spring Constant: " the constant of the variation between the force exerted by an ideal spring and spring's displacement."(Nelson, P.730)
Ideal Spring: " any spring that obeys the Hooke's law ,it does not any external or internal friction".(Nelson, P.727)
Elastic Potential Energy: " the potential energy due to the stretching or compressing of an elastic material". (Nelson, P.726)
Simple Harmonic Motion: "periodic motion in which the acceleration of the moving object is proportional to it's displacement".(Nelson, P.730)
Perpetual Motion Machine: " a machine that can operate forever without restarting or refuelling". (Nelson, P.729) 
Damped Harmonic Motion: " periodic motion effected by friction".(Nelson, P.726)

"Momentum and Collisions"
Linear Momentum: " a quantity that describes the motion of an object travelling in a straight line as the product of it's mass and velocity".(Nelson, P.728)
Impulse: "the product of force and time that acts on an object to produce a change in momentum".(Nelson, P.728)
Collisions: " the impact of one body with another".(Nelson, P.725)
Law of Conservation of Momentum:
Explosion: " a situation in witch a single object or group of objects breaks apart".(Nelson, P.726)
Elastic Collisions: " a collision in witch momentum and kinetic energy is conserved".(Nelson, P.726)
Inelastic Collisions: " a collision in witch momentum is conserved but kienetic energy is not conserved". (Nelson, P.727)
Head on elastic Collision: "an impact in witch two objects approach each other from opposite directions".(Nelson, P.727)
Glancing Collision: " a collision in witch the first object, after an impact with the second object , travels at an angle to the direction it was originally  travelling. "(Nelson, P.727)
