Regents Physics - Work, Energy & Power
Work, energy and power are highly inter-related concepts that come up regularly in everyday life. You do work on an object when you move it. The rate at which you do the work is your power output. And when you do work on an object, you transfer energy from one object to another. In this unit we'll explore how energy is transferred and transformed, how doing work on an object changes its energy, and how quickly work can be done.
- Define work and calculate the work done by a force.
- Calculate the kinetic energy of a moving object.
- Determine the gravitational potential energy of a system.
- Calculate the power of a system.
- Apply conservation of energy to analyze energy transitions and transformations in a system.
- Analyze the relationship between work done on or by a system, and the energy gained or lost by that system.
- Use Hooke's Law to determine the elastic force on an object.
- Calculate a system's elastic potential energy.
