Centripetal Force

Distance

symbol: s

unit: meter

formula: s=v*t s=r*(theta)

linear velocity

symbol: v

unit: m/s

formula: v=w*r v=s/t v=r*(theta)/t

linear acceleration

symbol: a

unit: m/s²

formula: a=(alpha)*r a=change in v/t

radius

symbol: r

unit: m

formula: r=s/(theta)

period

symbol: T

unit: secs

formula: T=2(pi)/w T=2(pi)/v

angular displacement

symbol: theta

unit: radians

formula: 1 revs = 2(pi) radians

angular velocity

symbol: omega (w)

unit: radians/sec

formula: w=v/r w=2(pi)/T

angular acceleration

symbol: alpha (a)

unit: radians/sec²

formula: alpha=a/r

centripetal acceleration

symbol: a(c)

unit: m/s²

formula: a(c)=v²/r a(c)=r*w² a( c)=4(pi)²r/T²

centripetal force

symbol: f(c)

unit: newtons

formula: f( c)=mv²/r f( c)=m*r*w² f( c)=4(pi)²*m*r/T²
