If the car’s motor requires 3600 joules to travel 10 meters, how far can it go in one minute under full sunlight?** When students today bring a solar-powered car to science fairs, they’re not just showing off gadgets—they’re joining a growing movement toward sustainable innovation. In a world increasingly shaped by clean energy trends and educational focus on climate solutions, projects like this reflect growing interest in renewable technology at the most community level. A student’s hands-on effort—harnessing sunlight to power motion—connects deeply with current conversations around energy independence and environmental responsibility. The solar panel on this prototype generates 180 watts of power per square meter across a 2.5-square-meter surface, delivering a total input of 450 watts (180 × 2.5). Under full sunlight conditions, this abundant energy is converted efficiently to drive the motor. Knowing the car’s motor demands 3600 joules to complete just 10 meters, we calculate how far the car can travel in one minute — equivalent to 60 seconds of sustained motion. With 450 watts available and the car consuming 3600 joules per 10 meters, the system efficiently draws power throughout the minute. Converting power to energy over time, the car has access to 450 joules per second (since 450 watts = 450 joules/second). Over 60 seconds,
