This law states that matter cannot be created or destroyed.
What is the Law of Conservation of Matter?
Energy of motion is called this.
What is kinetic energy?
A push or pull is called this.
What is a force?
A wave that requires a medium is called this.
What is a mechanical wave?
The flow of electric charges is called this.
What is electric current?
If a chemical equation is balanced, what is true about atoms on both sides?
What is the same number of each type of atom?
Stored energy is called this.
What is potential energy?
If forces are equal and opposite, the object is this.
What is balanced?
This part of a wave is the highest point.
What is the crest?
This material is best for making an electromagnet core.
What is iron?
A substance made of only one type of atom is called this.
What is an element?
As height increases, what happens to potential energy?
What is it increases?
What happens when net force is not zero?
What is motion changes (accelerates)?
If wavelength increases, what happens to frequency?
What is it decreases?
Increasing the number of coils in an electromagnet does what?
What is increases magnetic strength?
Why must coefficients be added when balancing equations instead of changing subscripts?
What is to keep the substance the same (changing subscripts changes the compound)?
Thermal energy is transferred by direct contact in this process.
What is conduction?
An object at rest will stay at rest unless acted on by a force. This is which law?
What is Newton’s First Law?
Bending of light as it passes through different materials is called this.
What is refraction?
What happens to current if resistance increases (same voltage)?
What is current decreases?
If a reaction has 4 oxygen atoms on one side and 2 on the other, what must happen?
What is add coefficients to balance oxygen atoms?
Why does convection occur in liquids and gases but not solids?
What is particles can move freely and carry energy?
Why does a heavier object require more force to accelerate?
What is greater mass requires more force (Newton’s Second Law)?
Why can electromagnetic waves travel through space but mechanical waves cannot?
What is EM waves do not require a medium?
Why does wrapping wire around a nail create a magnetic field?
What is moving electric charges create a magnetic field?
