Particles in all states of mater are in constant random __________.
Motion
The distance a wave oscillates (movement) back and forth from its resting position.
Amplitude
The force of attraction between objects.
Gravity
Energy from heat. Geothermal energy.
Thermal Energy
The first step in the scientific method.
Question
What is the smallest particle of matter? Hint: it consists of protons, neutrons, and electrons.
An atom.
The action of compressing or being compressed
(reduction in volume).
Compression
The amount of matter an object has.
Mass
Energy from matter that is unstable, found in the nucleus.
Nuclear Energy
The variable you choose to change.
Independent Variable
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.
The number of oscillations produced in a given time.
Frequency
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.
Resources that can be replenished.
Renewable
The outcome you can't control.
Independent variable
When a new substance is formed we call this a __________ change.
Chemical Change
The throwing back by a body or surface of light, heat, or sound without absorbing it.
Reflection
_______ = Distance divided by time
Speed
Energy in motion or in the position to move. Wind or hydroelectric energy.
Mechanical Energy
What is a hypothesis?
An educated guess.
Matter is anything that has ________ and takes up ____________.
Mass, space
The distance between one crest to another. The distance between waves.
Wavelength
Newtons 1'st Law
An object at rest will stay at rest while an object in motion will stay in motion unless acted upon by an outside force.
Energy stored in chemical bonds of molecules and compounds.
Chemical Energy
The constant variable.
