Document Summary
Express numbers in scientific notation and convert back and forth between scientific and standard notation. Understand how humans can tap into the force of gravity to get useful e(cid:374)erg(cid:455). Elate e(cid:374)erg(cid:455) to (cid:862)po(cid:449)er(cid:863) i(cid:374) the (cid:272)o(cid:374)te(cid:454)t of hu(cid:373)a(cid:374) ge(cid:374)eratio(cid:374) a(cid:374)d use of (cid:862)ele(cid:272)tri(cid:272)al po(cid:449)er(cid:863). Relate displacement, initial velocity, final velocity, acceleration, and time. Be able to solve for any one if three are known (and understand that this means that they are all interdependent!) Relate gravitational potential energy (gpe) to the acceleration due to gravity, height and mass. Relate gpe to kinetic energy (ke) once an object falls: understand the law of conservation of energy, and where useful energy can be lost. Know what factors affect the theoretical maximum energy available from a conventional hydroelectric dam, and calculate this maximum energy from the specifications of the dam and the water source. Understand where useful energy is lost in the process.
