Energy 1 Flashcards
1
Q
What is a system?
A
An object or a group of objects
2
Q
What happens to the energy in a system when the system changes
A
The energy store changes
3
Q
What are the energy store changes when a ball is thrown upwards?
A
Person throwing ball- kinetic energy (causes ball to rise)
Ball slows down and drops transferring kinetic energy into GPE (gravitational potential energy)
4
Q
What are the energy store changes when a moving object hits an obstacle?
A
The moving object has a store of kinetic energy
It transfers to other stores when it hits the obsticale and stops.
It could include stores e’g EPE (elastic potential energy) and vibrational energy as a sound is emitted
