Which of these quantities impact centripetal force? A. mass and speed only
B. mass and radius only
C. speed and radius only
D. mass, speed, and radius all impact centripetal force

D) Mass, speed and radius all impact the centripetal force

Explanation:

If we change either the mass, speed, and/or radius, then the centripetal force will be different. Though on rare occasions we could change the variables together in a way to have the centripetal forces line up, but in general the before and after forces will likely be different. Changing one variable at a time only will definitely result in a different centripetal force.

This is because the centripetal force F is determined by the formula

F = (m*v^2)/r

where,

m = mass

v = velocity

r = radius
