(13 cards)
Weight equation:
Weight= mass x gravitational field strength
Work done equation:
Work done= force x distance
Force applied to a spring:
Force applied to a spring= spring constant x extension
Distance travelled equation:
Distance travelled: Speed x time
Acceleration equation:
Acceleration= change in velocity over time taken
Resultant force equation:
Resultant force= mass x acceleration
Momentum equation:
Momentum= mass x velocity
Kinetic energy equation:
Kinetic energy= 0.5 x mass x speed squared
Gravitational potential energy equation:
Gravitational potential energy= mass x gravitational field strength x height
Power equation 1:
Power = energy transferred over time
Power equation 2:
Power= work done over time
Wave speed equation:
Wave speed= frequency x wavelength
Efficiency equation:
Efficiency= useful power output over total power input
