Introduction
This video provides a GCSE Physics revision lesson on kinetic energy. It explains what kinetic energy is, how to calculate it using a provided formula (which students must memorize for exams), and works through several example problems.
Key Takeaways
Kinetic energy is the energy stored in moving objects. A stationary object has zero kinetic energy.
The formula for kinetic energy is: KE (in Joules) = 0.5 * mass (in kg) * speed² (in m/s). This formula is not provided in exams, so students must memorize it.
The video provides worked examples demonstrating how to calculate kinetic energy given mass and speed, and how to calculate mass given kinetic energy and speed. It also shows how to convert Joules to Kilojoules.
