#potential energy notes

[er-cryptid]

Energy

-- kinetic energy formula: 1/2mv^2

-- kinetic energy requires motion

-- kinetic energy must be positive or zero; it cannot be negative

-- gravitational potential energy formula: mgh, where m = mass, g = gravity, and h = height

-- gravitational potential energy shows energy something could have

-- energy cannot be created or destroyed

-- the unit for energy is joules

-- joules is abbreviated as J
