KINETIC AND POTENTIAL ENERGY WORKSHEET Name:_____ Potential energy (PE) = mgh Kinetic energy (KE) = 1/2 m v2 Potential energy sample problem: A block is sitting on a platform 20 m high. It weighs 50 kg. ... (potential or kinetic) energy. Calculate it. 2. A car is traveling with a velocity of 40 m/s and has a mass of 1120 kg. The car has ...
An object gets potential energy from height, mass and gravity. An object with potential energy has the potential to do work. This potential is only released if the object falls. The energy is then trans-formed into energy of motion or transformed into work. Kinetic Energy Kinetic Energy is energy of motion. An object gets kinetic energy from ...

Chapter 4 Potential Energy and Kinetic Energy Practice Worksheet E p = mgh E k = ½ mv2 Weight of the object = mg in units of kg·m/s2 = N; where g = 9.8 m/s2 Units of Energy are Joules. J = N·m 1. A 50 kg boy and his 100 kg father went jogging. Both ran at aerate of 5 m/s. Who had more kinetic energy? 2.
Potential and Kinetic Energy 3.2 Potential energy is stored energy. The formula for the potential energy of an object is: where m equals mass in kilograms, g is the acceleration of gravity, and h equals the height of the object. The mass (m) of the object times the acceleration of gravity (g) is the same as the weight of the object in newtons. The
