Lesson: Work Done by a Constant ForceMathematics
In this lesson, we will learn how to calculate the work done by a constant force on a particle moving horizontally or vertically.
Sample Question Videos
Calculate the work done by a force of 5 N acting on a body that moved 10 m to the north if the force was acting south of west. State your answer in joules.
A body of mass 0.9 kg moved a distance of 25 cm while accelerating at 8 cm/s2. Find the work done .
A car of mass 1.5 metric tons was driving up a slope inclined to the horizontal at an angle whose sine is 0.3. The magnitude of the resistance to the motion of the car was 7 kg-wt per metric ton. If the car started moving from rest and accelerated uniformly over 15 seconds until it reached a velocity of 50 km/h, find the work done by the driving force while the car was accelerating. Take the acceleration due to gravity .
