KINETIC AND POTENTIAL ENERGY WORKSHEET. Potential energy: PE = mgh Kinetic energy: KE = 1/2 m v2 Total mechanical energy: ME = PE + KE. Practice problems: 1. A baby carriage is sitting at the top of a hill that is 21 m high. The carriage with the baby weighs 12 Kg. The carriage has ____________ energy. Calculate it.
Kinetic VS Potential Energy Practice Part 1: This graph shows a ball rolling from A to G. 1. Which letter shows the ball when it has the maximum kinetic energy? _____ 2. Which letter shows the ball when it has the maximum potential energy? _____ 3. Which letter shows the ball when it has the least potential energy? _____ 4.
ENERGY - POTENTIAL AND KINETIC WORKSHEET 1. Determine whether the objects in the following problems have kinetic or potential energy. Then choose the correct formula to use: KE= 1/2 m v2. PE = mass x gravity (10 m/s/s) x height. Energy= joules Weight= Newton Mass= kilograms Velocity= m/s Gravity’s acceleration= (10 m/s/s
Potential Energy is energy of position. 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 when the object falls. Kinetic Energy. Kinetic Energy is energy of motion.
The amount of kinetic energy in a moving object depends on its speed and its mass. x Kinetic energy can change into other forms of energy. x Potential energy is known as stored energy. x It is energy that could cause changes in the future. x Potential energy often changes into kinetic energy. Example Answer Key Examples of kinetic energy:
Solve the following word problems using the kinetic and potential energy formulas (Be sure to show your work!) Formulas: KE = 0.5 ·m· v 2 OR PE = m·g·h
