m = K.E / 0.5v 2. Calculate the potential energy of a car with a mass of 2,500 kg that is on a hill 100 meters above sea level. more kinetic energy . Kinetic energy: Potential energy: 1. faster. Kinetic energy depends on both. KINETIC AND POTENTIAL ENERGY WORKSHEET Name:_____ Determine whether the objects in the following problems have kinetic or potential energy. You serve a volley ball with a mass of 2.1kg. Kinetic Energy Potential energy is the gravitational pull on an object compared to how far it will fall. In classical mechanics, kinetic energy (KE) is equal to half of an object's mass (1/2*m) multiplied by the velocity squared. mass. Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. OR PE = mgh . = 1/2 m v 2. 1. Kinetic energy is energy possessed by an object in motion. (a) Calculate the potential energy of two singly charged nuclei separated by 1.00 × 10 −12 m by finding the voltage of one at that distance and multiplying by the charge of the other. (b) At what temperature will atoms of a gas have an average kinetic energy equal to this needed electrical potential energy? Then choose the correct formula to use: KE = 1/2 m v2. Use the equations for potential energy and kinetic energy. Where; m = Mass K.E. The book initially has only potential energy. Show your work in the space provided or on the back of this sheet. The greater the of a moving object, the it has. Kinetic Energy – what does it depend on? mass and velocity. Right before it hits the ground, all the potential energy will be converted to kinetic energy. The ball leaves your hand at 30m/s. The earth revolving around the sun, you walking down the street, and molecules moving in space all have kinetic energy. Can be transferred between objects: Cannot be transferred from one object to another: 2. The an object moves, the it has. Let’s solve an example; Find the mass when the kinetic energy is 320 and a velocity of 20. more kinetic energy . KINETIC AND POTENTIAL ENERGY WORKSHEET Name:_____ Determine whether the objects in the following problems have kinetic or potential energy. Potential Energy vs. Unreasonable Results. As it gains altitude hurtling to the ground, the potential energy levels increase. Calculating the Mass when Kinetic Energy and Velocity is Given. Kinetic and Potential energy calculations DRAFT 5th - 8th grade Therefore, the kinetic energy is 972 Joules (J). We can use the law of conservation of energy to set the initial and final energies equal. Is dependent on the mass and velocity of an object but, does not depend on the height: Depends on the mass, acceleration due to gravity and height of … You can use a potential energy calculator to work out what it is, how to calculate it, and how the formula works. Chemists divide energy into two classes. Kinetic Energy is the energy an object has owing to its motion. = Kinetic Energy v = Velocity. Then choose the correct formula to use: KE = 1/2 mass x velocity 2 (velocity is speed + direction) PE = mass x gravity x height ( weight x height) Show your work in the space provided or on the back of this sheet. Potential and Kinetic Energy Worksheet Kinetic Energy (KE) = ½ mass times velocity squared KE = ½ mv2 Potential Energy (PE) = mass times the acceleration due to gravity times height PE = mgh = N*h (g= 9.8 m/s2) 1 Newton (N) = 1kg*1m/s2 or 1kgm/s2 1. A 10 gram ball is rolling at 3 m/s. This implies that; K.E.
