# Equations Flashcards

average speed, distance travelled and time taken

speed = distance travelled ÷ time taken

speed = distance travelled ⁄ time taken

force, mass and acceleration

force = mass x acceleration

F = ma

acceleration, change in velocity and time taken

acceleration = change in velocity ÷ time taken

a = (v-u) / t

momentum, mass and velocity

momentum = mass x velocity

p=mv

density, mass and volume

density = mass ÷ volume

work done, force and distance moved

work done = force x distance moved (in direction of force)

energy transferred and work done

energy transferred = work done

kinetic energy, mass and speed

gravitational potential energy, mass, g and height

gravitational potential energy = mass x g x height

GPE = mgh

weight, mass and gravitational field strength

weight = mass x gravitational field strength

W = mg

pressure, force and area

pressure = force ÷ area

moment, force and perpendicular distance from pivot

moment = force x perpendicular distance from pivot

charge, current and time

charge = current x time

Q = It

voltage, current and resistance

voltage = current x resistance

V=IR

wave speed, frequency and wavelength

wave speed = frequency x wavelength
