Unformatted text preview: 1 Energy Energy Forms of energy Forms of energy Energy = the ability to do work Kinetic energy The energy of motion Potential energy The potential to do work Kinetic energy Kinetic energy K. E. = one-half the mass * the square of the velocity =1/2 mv 2 = kgm 2 /s 2 = joules Kinetic energy Kinetic energy K. E. = 1/2 mv 2 = kgm 2 /s 2 = joules If 4 cm of rain fell on 1 ha of land at a velocity of 8 m/s, what was the kinetic energy? Kinetic energy Kinetic energy K. E. = 1/2 mv 2 = kgm 2 /s 2 = joules If 4 cm of rain fell on 1 ha of land at a velocity of 8 m/s, what was the kinetic energy? K. E. = 0.5 * (10,000m 2 /ha * .04m * 1Mg water/m 3 ) *1000kg/Mg * (8m/s) 2 Kinetic energy Kinetic energy K. E. = 1/2 mv 2 = kgm 2 /s 2 = joules If 4 cm of rain fell on 1 ha of land at a velocity of 8 m/s, what was the kinetic energy? K.
