# Juan starts a campfire using wood and then sets a pot of water over the fire. Describe the major energy changes that take place in the wood, the pot, and the water.

This is a good thinking exercise. I will be happy to critique your thinking.

Hello this is my homework!!!!!!!!!!!!!

I am not going to do it for you. I will be happy to critique and check it for you, and offer suggestions.

I mostly guess on my answers all i know that is going to thermal energy that's it.

The idea here is that you need to learn to THINK and not GUESS. Think about the wood. How does it burn? Does it use oxygen? How? What are the products formed? Is the fire hot? What does it do to the pot and the water? Etc Etc Etc.

Ok i will try that.Thank you

What is mechanical energy?

## Mechanical energy refers to the energy possessed by an object due to its motion or position. It encompasses both kinetic energy, which is the energy associated with an object's motion, and potential energy, which is the energy stored in an object due to its position or condition.

To calculate mechanical energy, you can use the following equation:

Mechanical Energy = Kinetic Energy + Potential Energy

Kinetic energy (KE) can be calculated using the formula:

KE = 0.5 * mass * velocity^2

where mass refers to the object's mass and velocity is its speed.

Potential energy (PE) can be determined based on the type of potential energy involved. Some common types include:

1. Gravitational Potential Energy (PE_gravity) - This is the energy stored in an object when it is at a certain height above the ground and can be calculated using the formula:

PE_gravity = mass * gravitational acceleration * height

where mass is the object's mass, gravitational acceleration is approximately 9.8 m/s^2 (on Earth), and height is the vertical distance above a reference point.

2. Elastic Potential Energy (PE_elastic) - This is the energy stored in an object when it is deformed (e.g., compressed or stretched) and can be calculated using the formula:

PE_elastic = 0.5 * spring constant * (displacement)^2

where spring constant represents the stiffness of the material and displacement is the amount by which the object is compressed or stretched.

These are just a few examples of mechanical energy and its components. Depending on the context, other forms of mechanical energy may exist, such as rotational kinetic energy or energy associated with fluid flow.
