What is centripetal force...

• force that make the body move in straight with direction of acceleration

• force that make the body move in circular path with direction always towards the center of curvature

• force that make the body keep moving and keep stationary

This is the formula for....

 $F\ =\ \frac{mv^2}{r}$  

• Linear force

• Gravitational force

• Centripetal force

Relationship between radius of circle and centripetal force

• radius increase, force increase

• radius increase, force decrease

What can we derived from Newton's universal law of gravitation and centripetal force formula

• formula to determine mass of the earth and the sun

• formula to determine the acceleration

• formula to determine the gravitational force
