What happens to centripetal force when speed decreases, in the special case that the object continues moving in a circle of the same radius?

a)The force increases.
b)The force sometimes stays the same and sometimes decreases.  
c)The force also decreases.
d)The radius cannot stay the same.Speed does not affect centripetal force.

Answer #1

here,

the centripetal force , F = m * v^2 /R

m - mass of object

v - speed of object

R - radius of circle

when the speed decreases and the radius of circle remains the same

the centripetal force will decreases

so, the correct option is C) the force also decreases

    QUESTION 2 Remember that centripetal force and centripetal acceleration is the special name we give to the inwards force and acceleration that causes (forces) the object to move in a circle In the case of gravity where gravity causes a planet or satelite or star to orbit around another larger body, then gravity force is the centripetal force Centripetal force is the net force, and centripetal acceleration is the net acceleration. What is the centripetal acceler ation of a planet...
