Answer:
1.When the ball starts it has potential energy, therefore when it falls it will have kinetic energy.
2. When it falls it will have potential energy, then cut the scissors, therefor when it gets to the wood it will have kinetic energy.
3.when it slings shot it will fall into kinetic energy, then stop and stay at potential energy.

1) Chemical equation.
2) Types of reaction.
In the reaction above, we can see that two different compounds get together to form a new compound. <em>This is called a synthesis or a combination.</em>
Decomposition: A compound is broken down into simpler compounds.
Combustion: A compound containing Carbon and Hydrogen combines with oxygen.
Double replacement: Positive and negative ions in two compounds switch places.
