Equations Flashcards
Equation : force mass and acceleration
Force = mass x acceleration
Equations : acceleration
Force / mass
Or
Change in velocity / time
Equation: density mass volume
Density x volume
Equation : work done
Work done = force x distance moved in direction of force
Equation : energy transferred
Energy transferred = work done
Work done =force x distance in direction of force
Equation: kinetic energy
Kinetic energy = 1/2 x mass x speed squared
Equation : gravitational potential energy
Gpe = mass x g force x height
Equations : efficiency
Efficiency = useful energy out put / total energy input
Equation: mass , g , weight
Weight =mass x g force
Equation: pressure
Pressure x area
Equation: charge
Current x time
Equation: voltage
Current x resistance
Equation: electrical power
Voltage x current
Equation: wave speed
Frequency x length
Equations : speed distance time
Distance = speed x time
Whats the equation for power , energy and time ?
Energy
Power x time
