## Resource summary

 Question Answer Energy The ability to do work. Kinetic Energy The amount of energy something has because it's in motion (Energy in motion.) Kinetic Energy Formula $\frac{1}{2}mv^2$ Kinetic Energy Formula... m=___ v= ___ m= Mass v= Velocity Velocity The speed in which something moves or happens Joules The unit used to measure Kinetic Energy. Potential Energy Energy that is stored as a result of position and shape. (Stored Energy) Potential Energy Formula $mgh$ Potential Energy Formula... m=___ g=___ h=___ m= Mass g= Gravity (due to acceleration) h= Height Gravitational Potential Energy Potential energy that is stored in objects depending on their height. EXAMPLE: Diver on Diving Board What does gravitational energy depend on? Mass, Height, and Acceleration Elastic Potential Energy Potential energy that is stored when an object is deformed, stretched, or compressed. EXAMPLE: Shock-Absorbers on Bike Example of Kinetic and Potential Energy in Action Image: energy.PNG (image/PNG) Law of Conservation: Matter can't be created nor destroyed; however, it can be rearranged. Image: pe_ke.gif (image/gif) Mechanical Energy The energy associated with the motion and position of everyday objects. Example of Mechanical Energy Image: mec (image/jpg) Chemical Energy Energy stored in chemical bonds. Example of Chemical Energy Image: fi (image/jpg) Thermal Energy The total potential and kinetic energy of all the microscopic particles in an object.
