An atom. 

200

The action of compressing or being compressed 

(reduction in volume). 

Compression

200

The amount of matter an object has.

200

Energy from matter that is unstable, found in the nucleus.

Nuclear Energy 

200

The variable you choose to change.  

Independent Variable 

300

If you mix 20ml of salt and 20ml of water in a glass beaker, what will happen to the water over time? What type of change is this? 

The water will dissolve resulting in a physical change.  

300

The number of oscillations produced in a given time.

Frequency

300

True or False: If there is no movement in a system, forces are balanced. If there is movement, forces are unbalanced

What is True As long as everything in the system is not moving, the forces are equal, and therefore balanced.

300
