###### Potential Energy and Energy Conservation

Conservation of Mechanical Energy •For some types of problems, Mechanical Energy is conserved (more on this next week) • E.g. Mechanical energy before you drop a brick is equal to the mechanical energy after you drop the brick K 2+U 2 = K 1+U 1 Conservation of Mechanical Energy E 2=E 1

###### Physics Conservation of Energy Worksheet Solutions

Use conservation of energy. The initial spring potential energy is converted to kinetic energy. 1 2 kx2 = 1 2 mv2. (b) If the puck slides up a ramp angled at 30o above the horizontal, how far will it travel along the ramp, assuming negligible friction. Use conservation of energy again. Now all the initial spring potential energy is converted
