FAQs

Question: What is the difference between work and energy?
Answer: Work is the transfer of energy through force applied over a distance, while energy is the capacity to do work.

Question: How is power defined in physics?
Answer: Power is defined as the rate at which work is done or energy is transferred, typically measured in watts.

Question: Why is the conservation of energy important?
Answer: The conservation of energy principle states that energy cannot be created or destroyed, only transformed, which is crucial for solving many physics problems.
