Review the units of work, energy, force, and distance. Use the equations for mechanical energy and work to show what is work and what is not. Make it clear why holding something off the ground or carrying something over a level surface is not work in the scientific sense.

Work and Energy Equations. Difference Between and Work Energy. Frequently Asked Questions – FAQs. Work is given by the equation Fdcosθ, where d is the horizontal displacement over which the force acts and θ is the angle between the force and distance.
Explain work as a transfer of energy and net work as the work done by the net force. Explain and apply the work-energy theorem.
Work, Energy, and Power. Lesson 1 - Basic Terminology and Concepts. Definition and Mathematics of Work. Calculating the Amount of Work Done by Forces. Potential Energy. Kinetic Energy. Mechanical Energy. Power. Lesson 2 - The Work-Energy Relationship.
The principle of work and kinetic energy (also known as the work-energy theorem) states that the work done by the sum of all forces acting on a particle equals the change in the kinetic energy of the particle.
Use the work-energy theorem to find information about the forces acting on a particle, given information about its motion. We have discussed how to find the work done on a particle by the forces that act on it, but how is that work manifested in the motion of the particle?
