A car travels at a constant speed of 30 m/s. how much work does the car do if it travels from the time of 4500 s while utilizing 7800 N of force?

Two identical 82 mg dust particles very far apart (pee 0) are moving directly toward each other at a speed of 3698 m/s. the charge on each is-719 ? c. determine how close they will get to each other. let k = 9x109 n-m2/c2 & ignore gravity.

When the force acting on an object points at least partially in the direction of the motion the work done is considered to be negative

Area around a charged object where the objects can exert a force on another charged objects is an electric
