KINETIC AND POTENTIAL ENERGY WORKSHEET



Kinetic & Potential Energy PracticeFor questions 1-6, determine whether the objects in the following problems have kinetic or potential energy. Then choose the correct formula to use and solve. Show all work and include the appropriate units. You serve a volleyball with a mass of 2.1 kg. The ball leaves your hand with a speed of 30 m/s. A baby carriage is sitting at the top of a hill that is 21 m high. The carriage with the baby weighs 12 N. A car is traveling with a velocity of 40 m/s and has a mass of 1120 kg. A cinder block is sitting on a platform 20 m high. It weighs 79 N. There is a bell at the top of a tower that is 45 m high. The bell weighs 190 N. A roller coaster is at the top of a 72 m hill and weighs 966 N. What is the kinetic energy of a 3-kilogram ball that is rolling at 2 meters per second? What is the kinetic energy of a car that has a mass of 1000 kg and is moving at a speed of 30 m/s?If a motorcycle is moving at a speed of 22m/s and has a mass of 375kg what is the kinetic energy?Two objects were lifted by a machine. One object had a mass of 2 kilograms, and was lifted at a speed of 2 m/sec. The other had a mass of 4 kilograms and was lifted at a rate of 3 m/sec.Which object had more kinetic energy while it was being lifted?Which object had more potential energy when it was lifted to a distance of 10 meters? Show yourcalculation.What is the kinetic energy of a 2kg rabbit hopping at a speed of 1.25 m/s?The mass of a golf club is 0.6 kilograms. Suppose the club is traveling 2.0 meters per second. What is the club’s Kinetic energy? Calculate the kinetic energy of a car with a mass of 475kg rolling down a hill at a speed of 5m/s.What is the potential energy of an apple that 3.00-meters high with a mass of .5N?What is the kinetic energy of a 2,000-kilogram boat moving at 5 m/sec?In a lab investigation, one group of students (group A) measures the speed of a 0.1-kilogram car at 2.5 m/sec at the bottom of a hill. Another group of students (group B) measures the speed of the car at 3m/sec at the bottom of the hill. The car’s starting position at the top of the hill is one-meter high.What is the potential energy of the car at the beginning of the experiment before its speed is measured?Calculate the kinetic energy of the car for group A using the speed (2.5 m/sec) and mass values above.Calculate the kinetic energy of the car for group B using the speed (3.0 m/sec) and mass values above.You serve a volleyball with a mass of 2.1 kg.
