A swimmer jumps into a pool and does a cannonball, creating a big splash. Explain how energy exchanges as the swimmer hits the pool.

Potential energy of the swimmer is transformed into kinetic energy of the pool water splashing.

Changes in Energy

100

What is energy transfer?

The passing of energy from one object to another.

200

A cold block of metal is placed in contact with a warm block of metal. What type of energy will be transferred between the blocks?

thermal energy

300

How does mass and speed of an object affect the amount of kinetic energy an object has?                                                                                                                                                                                                                                                                                                   ,  

Larger mass and speed will provide a greater amount of kinetic energy

400

What is the law of conservation of energy?

Energy can not be created or destroyed

500

What is the energy transformation in a firework?

Chemical energy to kinetic and light/sound energy.

Temperature and Heat

100

What is heat?

Energy that is transferred between two objects at different temperatures

200

What is thermal energy?

A measurement of the total amount of kinetic energy of all particles in an object.

300

What is temperature?

The average kinetic energy in an object

400

What might cause food to not cook all the way through?

If the outside is heated too quickly, it will overcook before heat reaches the inside of the food.

500

If an oven is too hot, the bottom part of cookies on a metal tray can become hard and black. Why would the bottom of the cookies burn first?

The air and metal tray have the same temperature, but metal is a better conductor of heat than air is.
