Question

There is an equation to calculate centripetal force (向心力), which is

F = mv^2/r
where F is the centripetal force (in Newton)
m is the mass of the object (in kg)
v is the speed of the object (in m/s)
r is the radius of the circle (in m)

Centrifugal force (離心力) is an intertia force (or psuedo force) that appears in a non-intertia system, such as a rotating system. You may apply the above equation to calculate its magnetude in the non-inertia system.

Answer 1

There is an equation to calculate centripetal force (向心力), which is
用來計算向心力的方程式是

F = mv^2/r
where F is the centripetal force (in Newton) (這裏F是向心力(以Newton)做單位)
m is the mass of the object (in kg)(m 是物體的質量(以kg做單位))
v is the speed of the object (in m/s)(v是物體的速度(以 m/s做單位))
r is the radius of the circle (in m)(r 是圓形半徑(以m做單位))

Centrifugal force (離心力) is an intertia force (or psuedo force) that appears in a non-intertia system, such as a rotating system. You may apply the above equation to calculate its magnetude in the non-inertia system.

離心力是一種慣性的力(或假力(可以譯作虛力))，它會在一個非慣性系統裏出現，如正在旋轉的系統。你可以運用以上的方程式去計算它於非慣性系統的量。
