Sci:energy TOPIC 1 Flashcards
1
Q
Equations= Kinetic energy
A
Kinetic energy (J): K=1/2mass-KG X (Velocity=(distance-M/time-S))^2
Important note: PE lost= KE gained
2
Q
Equations: Gravitational potential energy
A
Gravitational potential energy:
Potential energy-J= mass-KG X gravity 10N/KG X height M
Important note: PE lost= KE gained
3
Q
Equations: Work done
A
Work done N/M OR J= ForceN X DistanceM
4
Q
Equations: Power
A
Power (watts)= work done (N/M or J)/ Time (seconds)
