Equations Flashcards
1
Q
Kinetic Energy
A
=0.5 x mass x velocity2
2
Q
gravitaional potential energy
A
= mass x gravitational field strength x height
3
Q
Power (4 equations)
A
= energy transferred / time
= work done / time
= potential difference x current
= current2 x resistance
4
Q
Efficiency ( 2 equations )
A
= useful energy / total energy
= useful power / total power
5
Q
Charge flow
A
= current x time
6
Q
energy transferred ( 2 equations )
A
= power x time
= charge x potential difference
7
Q
Density
A
= mass / volume
8
Q
Weight
A
= mass x gravitational field strength
