Final answer:
PE refers to Potential Energy, which is the energy possessed by an object due to its position or state. SBO stands for Spring-Block Oscillator, which is a system consisting of a spring and a block attached to it.
Step-by-step explanation:
In Physics, PE refers to Potential Energy and SBO stands for Spring-Block Oscillator.
Potential Energy (PE) is the energy possessed by an object due to its position or state. It represents the stored energy that can be released to do work. For example, when a book is lifted to a higher shelf, it gains potential energy as its height increases.
A Spring-Block Oscillator (SBO) is a system consisting of a spring and a block attached to it. When the block is displaced from its equilibrium position and released, it oscillates back and forth due to the spring's elastic force. The potential energy of the block is converted into kinetic energy as it moves.
