Atoms
The atomic number tells you the number of these subatomic particles.
What are protons?
The three phases of matter.
What are solid, liquid, and gas?
This type of energy is stored in food, fuel, or batteries and is released during chemical reactions.
What is chemical energy?
Distance ÷ Time
What is the formula for speed?
When a wave bounces off a surface, it’s called this.
What is reflection?
An object that does not conduct electricity.
What is an insulator?
In a neutral atom, the number of protons is equal to the number of these negatively charged particles.
This type of change does not create a new substance.
What is a physical change?
The movement of heat through direct contact, like a spoon getting hot in boiling water, is called this.
What is conduction?
An object in motion stays in motion unless acted upon by an unbalanced force.
What is Newton's 1st Law?
Sound waves need this to travel and without it, there’s no sound.
What is a medium?
Any material that attracts iron and materials that contain iron.
What is a magnet?
NH₃ is an example of this type of bond, where electrons are shared.
What is a covalent bond?
The formula for density.
What is density = mass ÷ volume?
A rock sitting on the edge of a cliff has this kind of energy because of its position.
What is potential energy?
Speeding up, slowing down, or changing direction.
What is acceleration?
This wave type moves particles side to side or up and down, like ocean waves.
What is a transverse wave?
A type of electrical circuit where all parts are connected one after another along on path.
What is a series circuit?
Isotopes of an element have the same number of protons but a different number of these.
What are neutrons?
What is a compound?
When wood burns in a fireplace, it transforms chemical energy into these two types of energy.
What are thermal and radiant energy?
The type of force that has an equal and opposite force and causes no acceleration.
What is a balanced force?
The number of compressions or vibrations per second in a sound wave is called this.
What is frequency?
This happens to the potential energy between two magnets when you move like poles closer together.
What is it increases?
This scientist proposed that all matter is made of tiny, indivisible particles called atoms.
Who is John Dalton?
Molecule kinetic energy increases as you increase it.
What happens as you increase thermal energy?
The heat transfer that occurs when warm air rises and cool air sinks is known as this.
What is convection?
The tendency of an object to resist a change in motion.
What is inertia?
This tool bends light and separates it into the colors of the rainbow.
What is a prism?
A device that transforms mechanical energy into electrical energy.
What is a generator?
This part of the atom contains most of its mass and is made up of protons and neutrons.
What is the nucleus?
Matter can not be created or destroyed.
What is the law of conservation of matter?
This type of energy transformation occurs when a battery powers a cellphone.
What is chemical energy to electrical energy?
An example of this law is a full shopping cart requiring more force to accelerate than an empty one.
What is an example of Newton's Second Law?
When two waves meet and create a bigger wave, it’s called this kind of interference.
What is constructive interference?
Moving a magnet through a coiled wire.
How do you create an electrical current with a magnet?
Metals tend to lose electrons and become these, because they have more protons than electrons.
What are positive ions (or cations)?
The physical property that determines matters ability to be hammered or rolled into flat sheets.
What is malleability?
When a car crash occurs, mechanical energy is mostly transformed into these two types of energy.
What are sound and thermal energy?
The attractive force between objects whose force depends on the objects mass.
This term describes the full range of all types of light waves, from radio to gamma.
What is the electromagnetic spectrum?
Loop a conductive wire more times around a metal rod.
How do you increase the strength of an electromagnet?
