Work is the transfer of energy from one object to another. It is measured in Joules and is equal to the force applied to an object multiplied by the distance it moves. There are two types of work: * **Kinetic work** is the work done to accelerate an object. * **Potential work** is the work done to raise an object against gravity. Power is the rate at which work is done and is measured in Watts. * **Average power** is the total work done divided by the time it takes to do the work. * **Instantaneous power** is the power at a particular instant in time. Non-conservative systems can lose energy through work, while conservative systems do not. In this episode, we will learn the two equations for work and how to calculate kinetic and potential energy. We will also learn the two equations for power and how to use them to calculate the rate at which energy is converted from one type to another.
A system has a potential energy of 20 Joules and a kinetic energy of 15 Joules. What is the total mechanical energy of the system?
What is the equation for average power?
