Forces & Motion
The push or pull that acts on an object, changing its speed or direction.
What is a force?
The ability to do work.
What is energy?
The smallest piece of matter that has the properties of an element.
What is an atom?
A process that rearranges atoms to form new substances.
What is a chemical reaction?
A large molecule made up of many smaller molecules bonded in a repeating pattern.
What is a polymer?
The relationship between an object’s mass and the change in its motion when hit by a force.
What is Newton’s Second Law?
Energy stored in the bonds between atoms and molecules.
What is chemical energy?
Two or more atoms bonded together.
What is a molecule?
A process where energy is absorbed from the environment.
What is an endothermic reaction?
The type of material that is made through chemical processes by humans.
What is a synthetic material?
When two marbles collide, energy is transferred from one to the other. This is an example of what kind of energy?
What is kinetic energy?
The motion of atoms and molecules in a substance as its temperature increases.
What is thermal energy?
A substance made of only one kind of atom.
What is an element?
A process where energy is released into the environment.
What is an exothermic reaction?
Changing the amount of sodium borate in the polymer lab changes what property of the polymer ball?
What is its bounciness?
This happens when the forces on an object are not equal, causing a change in motion.
What is an unbalanced force?
The type of energy stored in an object due to its position or condition.
What is potential energy?
An observable or measurable characteristic of a substance.
What is a property?
The principle stating that the total number of atoms does not change in a chemical reaction.
What is the conservation of mass?
The small molecules that link together to form a polymer.
What are monomers?
The term for a connected set of parts that work together as a whole in an experiment.
What is a system?
The scientific principle stating that energy cannot be created or destroyed, only transformed.
What is the conservation of energy?
The process of combining atoms to form new substances with different properties.
What is a chemical reaction?
When two substances combine to create concrete, this is evidence of what?
What is a chemical change?
The type of energy change that occurs when glue and borax combine to form a polymer.
What is a chemical reaction releasing or absorbing energy (exothermic or endothermic)?
