Why it matters
This objective helps connect Changes in energy to exam-style questions, flashcards, and revision notes for Energy changes in a system, and the ways energy is stored before and after such changes.
Quick student answer
What are the variables in the required practical: investigate the transfer of energy from a gravitational potential energy store to a kinetic energy store?
Direct answer
In Physics, this page helps you handle practical questions about required practical: investigate the transfer of energy from a gravitational potential energy store to a kinetic energy store in Energy changes in a system, and the ways energy is stored before and after such changes. Focus on the independent, dependent and control variables, the method, and how the evidence supports a conclusion. Key terms to check are gravitational potential energy and kinetic energy.
Key terms
- gravitational potential energy: The energy stored in an object due to its height above the ground.
- kinetic energy: The energy an object possesses due to its motion.
Common trap
Confusing gravitational potential energy with kinetic energy: Explain that as the object falls, gravitational potential energy is converted into kinetic energy; at the moment of impact the energy is predominantly kinetic, with potential energy reduced to zero
