No, the sun is not a mechanical energy source. It is a star that emits energy through nuclear fusion reactions in its core, converting hydrogen into helium and releasing a vast amount of energy in the form of heat and light.
No, the energy from the sun travels to Earth mainly in the form of electromagnetic radiation, such as sunlight. This energy is transformed into other forms of energy, such as heat and light, when it interacts with Earth's atmosphere and surface.
False. Plants convert radiant energy from the sun into chemical energy through the process of photosynthesis, not mechanical energy. This chemical energy is then used for various cellular processes, including growth.
A simple example is solar energy. The only energy received by the earth from the sun is radiant energy. This heats the air on the earth creating convection currents, or wind. This wind is a mechanical energy.
A running car engine requires energy but is not a living thing. The engine converts fuel into mechanical energy to power the vehicle.
Total energy is the sum of the kinetic and potential energy in a mechanical system that has no external forces, e.g. a planet in orbit round the Sun.
False. The energy from the Sun comes in the form of electromagnetic waves. Those are not mechanical waves.

It goes from light energy from the sun to chemical energy to chemical, mechanical, and heat energy and the chemical energy can go to mechanical and heat energy. Then the remaining chemical energy goes to chemical, heat, and mechanical energy again and it keeps on repeating.
Plants use radiant energy from the sun in the process of photosynthesis to convert carbon dioxide and water into glucose and oxygen. This glucose provides energy for plant growth and development, and oxygen is released as a byproduct. Mechanical energy is not involved in this process.
No, it is electrical and light energy, which transforms into heat energy.

Motors convert electrical energy to mechanical energy. Generators transfer mechanical energy to electrical energy.
