You get to learn about the conservation of energy laws through real-life examples. Perform experiments with falling objects and calculate the changes in mechanical energy that occur.
After completing this tutorial, you will be able to complete the following:
What type of radiation is visible to the human eye?
~ We can visually detect electromagnetic radiation from high-temperature objects like lamps or electric heaters.
How can radiation be detected from low-temperature living or non-living objects?
~ Radiation from low-temperature or non-living objects can be seen using a thermal imaging camera.
Explain how the sun heats the Earth.
~ Radiation, in the form of electromagnetic rays, is given off by the sun, and travels to the Earth. The energy from these rays is absorbed by the Earth and thus warms the Earth's surface.
