Equations Flashcards
The equation that links weight, mass and gravitational field strength
Weight = mass x gravitational field strength
The equation that links work done, force and distance
Work done = force x distance
The equation that links force applied to a spring, the spring constant, the extension
Force applied = spring constant x extension
The equation that links moment, force and distance
Moment = force x distance
The equation that links pressure, force and area
Pressure = force / area
The equation that links distance travelled, speed and time
Distance = speed x time
The equation that links acceleration, change in velocity and time
Acceleration = change in velocity / time
The equation that links resultant force, mass and acceleration
Resultant force = mass x acceleration
The equation that links momentum, mass and velocity
Momentum = mass x velocity
The equation for kinetic energy
Kinetic energy = 0.5 x mass x speed ^2
The equation that links gravitational potential energy, gravitational field strength, mass and height
Gravitational potential energy = gravitational field strength x mass x height
The equation that links power, energy transferred and time
Power = energy transferred / time
The equation that links power, work done and time
Power = work done / time
The equation that links energy transferred, power and time
Energy transferred = power x time
The equation for efficiency
Efficiency = useful energy / total energy transfer
