A car moves with a uniform velocity (v) in a particular direction for a distance for a distance (s) under in the same direction. The work done by the force will be:
Fs
The correct answer is option 3 i.e. Fs.
When a car moves with a uniform velocity (v) over a distance (s) in the same direction as the applied force, the work done by the force is given by the formula Work = Force × Displacement. Since the velocity is uniform, net force balances friction and air resistance, ensuring constant motion. The applied force and displacement being in the same direction makes the angle 0°, so cos 0° = 1. Thus, Work done = Force × s × 1 = Force × s. The work done is positive, and it results in transfer of energy to maintain motion.
