Chapter 5 - Work Energy Power
In the GCE A Levels, we appreciate that energy and work are essentially the same quantity and both are measured in Joules, but there is a very nuanced difference in the two and this video will explore this.
We can calculate the work done by a force by taking the average magnitude of that force multiplied by the distance moved in the direction of that force. In the GCE A Levels, we will be required to consider situations where the force is directed in various directions, including opposite to the distance moved. This video will discuss these scenarios and how to tackle them.
In the GCE A Levels, we are required to understand how the expression for gravitational potential energy is derived from the concepts of work done. This video will discuss this derivation.
