Lesson: Power as the Rate of Work Mathematics • Third Year of Secondary School

Students will be able to

• understand that power is the time derivative of work,
• distinguish between instantaneous power and average power,
• calculate the power of a force by taking the time derivative of work,
• calculate the power of a force by taking the time derivative of the scalar (dot) product of force and displacement,
• calculate the amount of work done over a period of time by taking the definite integral of power.
