Kinetic Energy Worksheet with Answers - Free Printable

['Potential energy is energy of position. It is calculated as Ep = mgh, where m is mass in kilograms, g is the acceleration due to gravity (9.8 m/s²), and h is height in meters.', 'The formula for potential energy shows that it increases with mass and height.', 'An object with potential energy has the potential to do work, which is transformed into other forms of energy when released.', 'The example shows that a 4 kg object at 5 m height has Ep = (4 kg)(9.8 m/s²)(5 m) = 196 Joules.', 'Kinetic energy is energy of motion, calculated as Ek = (1/2)mv², where m is mass in kilograms and v is velocity in meters per second.', 'Kinetic energy increases with mass and the square of velocity.', 'The example shows that a 10 kg object moving at 10 m/s has Ek = (1/2)(10 kg)(10 m/s)² = 500 Joules.', 'The conversion of potential energy to kinetic energy occurs when an object falls, such as in hydroelectric dams or when a cyclist goes down a hill.', 'The faster an object moves, the more kinetic energy it has, which helps overcome gravity and get up a hill.']
