Calculate Kinetic and Potential Energy in Physics Problems.
Start studying Calculating Potential Energy (PE) and Kinetic Energy (KE). Learn vocabulary, terms, and more with flashcards, games, and other study tools.
Calculating PE and KE 1. What is the PE of a 2 kg block 5 m above the floor? 2. What is the PE of a 3 kg ball that is 2 m above the floor? 3. Joe throws a 4 kg stone straight up and it reaches a height of 5 m. What is its PE at its highest point? 4. Which has more PE, a 6 kg ball at 6 m or a 7 kg rock at 5 m in height? 5. Which has more PE, a 2.5 kg book at 4 meters or a 1 kg paperweight at 8.
The processed data includes calculations for velocity, kinetic energy (KE), potential energy (PE), and total energy (E) for each of the measuring points using the trial averages of your raw data. In the Supplemental Data section, calculate the change in potential, kinetic and total energy between each two positions by subtracting the energy at the first position from the energy at the second.
How to use the take home pay calculator. To find out your take home pay, enter your gross wage into the calculator. The wage can be annual, monthly, weekly, daily, or hourly - just be sure to configure the calculator with the relevant frequency. By default, the calculator selects the current tax year, but you can change this to a previous tax year if desired. It also defaults to 5 working days.
Calculate how much are KE, PE and E (total energy) of an object dropped from 5m when is 3m above the. ground.
Calculate. the kinetic energy of a moving object. 3. Determine. the gravitational potential energy of a system. 4. Calculate the power of a system. 5. Apply conservation of energy to analyze energy transitions and transformations in a system. 6. Analyze. the relationship between work done on or by a system, and the energy gained or lost by that system. 7. Use Hooke's Law to determine the.
This activity demonstrates how potential energy (PE) can be converted to kinetic energy (KE) and back again. Given a pendulum height, students calculate and predict how fast the pendulum will swing by understanding conservation of energy and using the equations for PE and KE. The equations are justified as students experimentally measure the speed of the pendulum and compare theory with reality.
