Equations Flashcards
Weight, mass and gravitational field strength
W= m x g
Work done, force and distance
W = fxd
Force applied to a spring, spring constant and the extension
F= kxe
Moment force and distance
M= fxd
Pressure, force and area
P= F/a
Distance travelled, speed and time
Distance =speed x time
Acceleration, change in velocity and time taken
A = change in velocity / time taken
Resultant force, mass and acceleration
Resultant force = m x a
Momentum, mass and velocity
Momentum = m x v
Kinetic energy
0.5 x mass x speed^2
Gpe, gravitational field strength, mass and height
Gpe=gravitational field strength x mass x height
Power, energy transferred and time
Power = e/t
Power, work done and time
P= work done/time
Energy transferred, power and time
Energy transferred= power x time
Efficiency
Output/ input
