Equation Flashcards
Equation for work done distance and forc
Work done (energy transferred) = force x distance
What is the equations that relates to change in gravitational potential energy
Ep(J)= mass X gfs (N/kg) x Change in height
Equation for efficiency
Efficiency= useful output energy / total output energy(J) x 100
Equation for power
Power = energy transferred divide by time taken
Equation for power in electricity measured in watts
Power= Current x potential difference
Equation for power when given resistant but not the voltage
Power= current 2 x resistance
Equation that links charge flow, current and time
Q(charge flow in COULOMBS)= current x time
Equation linking voltage and chargw
Voltage= energy transferred/ charge
Equation to find the resistance
Resistance= voltage/ current
Equations for density
Density= mass/ volume
SUVAT what do they mean
A= acceleration m/s2 V= final velocity m/s S= displacement(distance) meters U= initial velocity m/s T= time seconds
What is the equation (SUVAT) for final velocity
V= s/t
Equation( SUVAT) for acceleration
A= v - u divide by time
Equation for resultant for force
RF= mass x acceleration
Equation for mass
Weight= mass x gfs
