TED-Ed: How does workwork? - Peter Bohacek

The video tutorial explains the concepts of work and power in physics. Work is the energy transferred into or out of a system, measured in joules. An example using a grandfather clock illustrates how work is calculated by multiplying force and distance. Power, the rate of energy transfer, is measured in watts. The tutorial discusses James Watt's contribution to the concept of horsepower and compares the power needed to run a clock versus a 100-watt light bulb. It concludes with a calculation of the clock's power usage over five days, highlighting the efficiency of energy use.

How much power does the grandfather clock use compared to a 100-watt light bulb?

What happens to the energy stored in the clock when it runs?
