Applied Mechanics and Graphic Statics
When a body slides down an inclined surface, the acceleration (f) of the body, is given by

f = g sin θ

f = g cos θ

f = g

f = g tan θ

f = g sin θ

f = g cos θ

f = g

f = g tan θ

Applied Mechanics and Graphic Statics
If a particle moves with a uniform angular velocity ‘ω’ radians/sec along the circumference of a circle of radius ‘r’, the equation for the velocity of the particle, is

v = ω √(r² - y²)

y = ω √(y - r)

v = ω √(r² + y²)

v = ω √(y² - r²)

v = ω √(r² - y²)

y = ω √(y - r)

v = ω √(r² + y²)

v = ω √(y² - r²)
