Name ________________________________________ Date _______________ Energy Worksheet 1) You are at the park and you climb a tree. You sit on a branch 10 meters above the ground and enjoy the view. Your mass is 50 kg. What is your gravitational potential energy? 2) You fall off of the tree branch and on to the ground. Your mass is still 50 kg, and you fall at a speed of 10 m/s (ouch). What is your kinetic energy? 3) You are holding an egg in your hand. Your hand is 2 m above the ground. The egg has a mass of 0.2 kg. What is the gravitational potential energy of the egg? 4) The egg that has a mass of 0.2 kg falls to the ground. It falls with a speed of 3 m/s. What is its kinetic energy?
What form of energy does each of the following have? You may choose more than one form if it is appropriate. A toaster? __________________________ Your bagel for breakfast? __________________________ Your mp3 player? __________________________ The sun? __________________________ A fire? __________________________ A bird flying? __________________________ An apple? __________________________ A Nintendo Wii? __________________________
