Power
Leaving Cert Physics · Forces and Motion
Higher Level
The rate at which energy is transferred or converted from one form into another, measured in watts, where one watt is one joule per second. Two machines can transfer the same energy, but the more powerful one does it in less time.
Ordinary Level
The energy transferred each second, measured in watts. A 2000 W kettle uses energy far faster than a 60 W lamp.
