science - POTENTIAL ENERGY AND KINETIC ENERGY

• energy - is the ability or capacity to do work
• joule (J) - what is the unit for energy and work?
• potential energy - the energy stored in an object or substance which is based on its position, arrangement or state
• kinetic energy - is the energy of an object in motion
• elasticity - is the ability of a deformed material to return to its original form, shape or size after removing the force that causes deformation
• density - is the intrinsic property of any object, it is an object's mass per unit volume
• reflection - described as the turning back of the wave as it hits a barrier
• reverberation - multiple reflections or echoes in a certain place
• refraction - is the change in direction of sound waves as they pass from one medium to another
• dispersion - is a kind of refraction which provides us colors of light
• optical density - refers to the measurement of a components ability to slow down the transmission of light
• prism - material that separates the color of light
• melting - is the process of changing solid into liquid
• solidification or freezing - is the process of changing liquid to solids
• evaporation - is the process of changing liquid into gas
