Molecules
A group of two or more atoms joined together.
What is a molecule?
When electrical charges build up on the surface of an object.
What is static electricity?
This is any object that can attract iron, nickel, or cobalt.
What is a magnet?
This is the energy due to motion.
What is kinetic energy?
These two forces of nature resist all motion of objects.
What are gravity and friction?
This is made from a chemical change or chemical reaction.
What is a compound?
This is the continuous flow of electrons around a circuit.
What is current electricity?
This is the area of magnetic force around a magnet.
What is a magnetic field?
This is the distance an object travels divided by the amount of time it takes for that object to travel that distance.
What is speed?
An object tends to stay at the same velocity unless another force causes it to change.
What is the first law of motion, or the law of inertia?
This type of bond is formed when atoms share valence electrons.
What is a covalent bond?
This is a circuit that has two or more paths for electrons to flow.
What is a parallel circuit?
This is a coil of wire with a core attached to an electrical source.
What is an electromagnet?
This is the speed of a moving object in a certain direction.
What is velocity?
This is the law that states force is equal to the mass of an object times its acceleration.
What is Newton's second law of motion?
This type of bond is formed when one atom gains or loses an electron to another atom.
What is an ionic bond?
The number of watts divided by the number of volts equals the number of amperes.
What is the relationship between amperes, volts, and watts?
This is a change in velocity during a period of time.
What is acceleration?
When one object exerts a force on a second object, the second object exerts an equal in magnitude and opposite in direction force on the first object.
What is Newton's third law of motion?
Chemical symbols and numbers show the elements in the specific ratios that make up these.
What is a chemical formula?
This device stores chemical energy that can be released when the chemical reaction between metals and the electrolyte releases electrons to travel around a circuit.
How does a battery work?
This is the mass and velocity of a moving object.
What is momentum?
