What is the work done by a centripetal force on an object moving in a circular path at constant speed?
The work done by a centripetal force is zero because the force acts perpendicular to the direction of motion, meaning there is no displacement in the direction of the force.

...2852 + 7848 + 2962 + 4268 = ? – 1460
(25 + 12) x 6 + 34 = ? + 18
9/5 × 18/25 ÷ 42/21 = ? - 82/75
32 × 3 (54 – 15) + 186 ÷ 3 ÷ 2 – (21)² =?
