Energy in Physics

Video Summary

Work is the transfer of energy from one object to another. It is measured in Joules. There are two types of work: - Conservative work: the work done by a conservative force, such as gravity or the spring force. - Non-conservative work: the work done by a non-conservative force, such as friction. Power is the rate at which work is done. It is measured in Watts.
