Flashcards do conjunto (5)
- 1What is the equation for Kinetic energy? What unit is energy measured in?K.E = 1/2 x mass x speed^2
joules (J) - 2What is the equation for GPE? What does GPE stand for?mass x gravitational field strength X height
GPE = mgh
GPE is gravitational potential energy - 3What are the two equations for power?power = work done / time taken
P = W/t
power = Energy transferred / time taken
P= E/t - 4What is efficiency in terms of power?Useful power output / total power input
- 5What is efficiency in terms of energy transfer?useful energy output / total energy input
