Equations Flashcards
(Weight equation)
Weight= mass x gravitational strength
(Work done equation)
Work done= force x distance (along a line of action of the force)
(Spring equation)
Force applied to a spring= spring constant x extension
(Moment Equation)
Moment= force x distance
(Pressure Equation)
Pressure= force normal to a surface/area of that surface
(Distance Equation)
distance travelled= speed x time
(Acceleration Equation)
acceleration= Change in velocity/time taken
(Resultant Force Equation)
Resultant Force= mass x acceleration
(Momentum Equation)
Momentum= mass x velocity
(Kinetic Equation)
Kinetic Energy= 0.5 x mass x (speed) squared
(gravitational Equation)
gravitational potential energy=mass x gravitational field strength(g) x height
(Power Equation)
Power= energy transferred/time
(Power Equation)
Power= work done/time
(Energy Equation)
Energy transferred= power x time
(Efficiency Equation)
Efficiency= useful power output/total power output
(Wave Speed Equation)
Wave speed= frequency x wavelength
(Density Equation)
density= mass/volume
(Charge Equation)
Charge flow= current x time
(Potential Difference Equation)
potential difference= current x resistance
P=V I
Power=potential difference x current
(Power Equation)
Power= (current)squared x resistance
(Energy transferred Equation)
Energy transferred=charge flow x potential difference
