Body mass index= mass in kg height in meters2
slope= ( y2 − y1 ) ( x2 − x1 )
Volume V = length l × width w × height h

mass m = density ρ × Volume V
ρ= m V

distance d = velocity ѵ × time t
ѵ= Δd Δt
a = Δѵ Δt = ( v2 − v1 ) ( t2 − t1 )
ѵ = at
d = ½at²
d = ½gt²
where g is the acceleration of gravity, g = 980 cm/s²

Gravitational Potential Energy GPE = mgh
Kinetic Energy KE = ½mѵ²

momentum = mass m × velocity ѵ
Force F = mass m × acceleration a

Actual Mechanical Advantage = Load lifted ÷ Force used to lift
efficiency= Actual Mechanical Advantage Ideal Mechanical Advantage
