AQA GCSE Physics- Energy
Energy - correct answer ✔the capacity of a physical system to do work,
never used/created, only transferred between different stores
How is energy transferred? x3 - correct answer ✔mechanically, electrically,
by heating/radiation
Energy transferred mechanically - correct answer ✔by a force doing work
Energy transferred electrically - correct answer ✔work done by moving
charges
Energy transferred through heating/radiation e.g. - correct answer ✔light,
sound
System - correct answer ✔a group of objects you are interested in
What happens when a system changes? - correct answer ✔energy is
transferred into/away from system, between different objects, between
different energy store types
Closed systems - correct answer ✔matter/air cannot enter/leave system, net
change in closed systems total energy is always 0
, E.g. of energy being transferred by heating - correct answer ✔boiling water
in a kettle
Work done - correct answer ✔energy transferred, work is done when current
flows (against the resistance in a circuit) / by a force moving an object
Which store does energy go to from movement? What does the energy
depend on? - correct answer ✔kinetic, depends on objects mass and speed
Kinetic energy formula - correct answer ✔
Ek - correct answer ✔Kinetic energy(J)
M - correct answer ✔mass(Kg)
V - correct answer ✔speed(m/s)
Which store does energy go to from raised objects? What does the energy
depend on? - correct answer ✔gravitational potential, mass, height and
strength
what does lifting an object in a gravitational field require? - correct answer
✔work
Gravitational potential energy formula - correct answer ✔Ep=MGH
Ep - correct answer ✔gravitational potential energy(J)
