l (distance) = m
t (time) = s
m (mass) = kg
a (area) = length(meters) x width(meters) sign is meters squared
v (velocity) = m(meters)divided by time(seconds) m/s
(density) = mass(kg) divided by volume( length(m)x width(m)x height(m)) m/v
g (gravity) = -9.8 meters per second squared
F (force) = m(mass) x a(acceleration= meters per second per second m/s squared)F=MA
E (energy) = may have many different equations, most famous is Einstein's E = mc2, where E= rest mass energy
P (power) = work(work= force x distance x cosO) divided by time
