Final answer:
The transfer of energy by motion against an opposing force is indeed work, which is true. Energy can be transferred as heat or work, and it requires force and movement of an object over a distance. Work is also path dependent and can involve overcoming resistance or changing system volume.
Step-by-step explanation:
Work and Energy Transfer
The statement that work is the transfer of energy by motion against an opposing force is true. Work involves applying a force to an object, which then moves the object over a distance. This concept is crucial in understanding how energy is transferred within a system. For example, when energy is transferred from your body to a shopping cart as you push it, this is an example of work being done. Additionally, the transfer of energy from a wave to your board when surfing is another representation of work.
As for the forms of energy that can be used to do work, heat, work, and internal energy are all able to do work on a system. This reinforces that energy can be transferred in various forms, whether it's mechanical work, electrical currents, or heat transfer due to temperature differences.
It's important to note that work requires not just the exertion of force, but the actual movement of an object. It's also path dependent and can involve working against an external force or to increase the volume of a system.
