forces equations

weight (W)

weight (W)

mass (m)x gravitational field strength (g)

work done (W)

force (F) x distance (s) (moved along the line of action of a force)

force (F)

spring constant (k) x extension (e)

moment of a force (M)

force (F) x distance (d) (perpendicular to the direction of the force)

pressure (p)

force normal to a surface (F) / area of that surface (A)

distance travelled (s)

speed (v) x time (t)

acceleration (a)

change in velocity (△v) / time taken (t)

=

final velocity - initial velocity (v-u) / time taken (t)

resultant force (F)

mass (m) x acceleration (a)

momentum (p)

mass (m) x velocity (v)

pressure (p)

height of column (h) x density of liquid (ρ) gravitational field strength (g)

(final velocity)² - (initial velocity)²

2 x acceleration (a) x distance (s)

force (F)

change in momentum (m△v) / time taken (t)
