Unit 6 Variables

kinetic energy: energy of motion (J)

gravitational potential energy: energy stored in a gravitational field (J)

spring potential energy: energy stored in something squished or stretched (J)

thermal energy (J)

Mechanical energy of a system; changed by external work, collisions, or a heat source (J)

when calculating [Δ]DeltaU_g: height change of the center of mass (m)

compression/stretch of spring from equilibrium (m)

Spring constant (N/m)

gravitational field strength (m/s² or N/kg)

work: a change in mechanical energy (J)

[ΣE]SigmaE= K
