Equations Needed To Know Flashcards
Equation between weight, mass and gravitational field strength.
Weight= Mass x Gravitational Felid Strength.
Equation for work done, distance and force
Work Done= Force x distance
Equation for force applied to spring
Force= Spring Constant x Extension
Equation for Pressure, Force and Area
Pressure= Force x Area
Equation for pressure and surface
Pressure = force normal to a surface/area of that surface

Distance Travelled= speed x time
Equation for acceleration, change velocity and time
Acceleration= change in velocity / time take
Equation for resultant, mass and acceleration
Resultant force = mass x acceleration
Equation for momentum, mass and velocity
Momentum = mass x velocity
Kinetic energy=
0.5 x mass x speed2
Equation for gravitational potential energy
Mass x gravitational strength x height
Equation for power, energy and time
Power= energy transferred / time
Equation for power, work done and time
Power= work done / time
Equation for energy, power and time
Energy transferred = power x time
Equation for efficiency and energy transfer
Efficiency = useful output energy transfer / total input energy transfer
