  1. A rock climber wears a 7.5kg backpack while scaling a cliff. After 30 minutes the climber is 8.2m above the starting point. How much work does the climber do on the backpack? A person is lifting a bag over their head then places it on the floor. What kind of work is being done? Concept question: potential energy work Math question: W= 600j W=∆E Page 8: Solutions Page 7: Math question Page 6: Concept Question Page 4: Potential Energy Page 2: what it means Page 3: the big idea Page 5: Kinetic Energy KE work is used when there is a velocity change. PE work is used when there is an elevation change. Doing work changes the amount of energy an object has. In order to do work one must apply a force Measured in Joules W= ∆E work Change in energy
