Bouncing Ball Experiment
Therefore the ball ends up with more GPE. In short: GPE=Mass (kg) × Gravitational Field Strength (N/Kg) × Height (m) If we let mass = m. Gravitational Field Strength = g. Height = h1. An increase in h1, assuming g and m stay constant, results in an increase in m × g × h1 which results in an increase in GPE.

There are 2 principles to grasp: 1. Energy will only travel between energy stores; it will not "stop" part way between the stores and it won''t travel to something that isn''t an energy store. 2. Energy will only travel on certain energy "pathways". The first rule is pretty obvious, I hope, so no more needs to be said.

Topic 4 Energy Resources and Transfers
Energy transfers. Energy can be transferred between different stores including chemical, kinetic, gravitational, elastic, thermal, magnetic, electrostatic and nuclear as a result of an event or process. Energy can be transferred in various ways including: Mechanically e.g. when gravity accelerates an object and gives it kinetic energy.

Energy stores and systems
Energy Stores. Energy can be stored in various ways within a system. Here are the primary stores you should know about: Kinetic Energy: The energy of motion. The faster something moves, the more kinetic energy it has. Gravitational Potential Energy: Energy stored due to an object''s position in a gravitational field.
I''ve Dropped My Power Bank
You can test your power bank to see if it is working after being dropped. You should replace your power bank if it has been dropped and the following issues are present if: The external shell is damaged or cracked. There is a difference in the temperature, or the power bank is heating up abnormally whilst charging.
Energy stores and energy transfers
Energy can be described as being in different ''stores''. Energy cannot be created or destroyed, but it can be transferred from one energy store to other energy stores. Some energy transfers are ...
