The amount of matter in an object. It's measured in grams.
Mass
What is a system?
A system is a group of related parts that make up a whole and can carry out functions its individual parts cannot.
The “must-have” parts of a solution to a problem. These parts must be done in order to have a possible solution.
Constraints
The “like-to-have” parts of a solution to a problem. These parts let us compare solutions and decide if one solution is better than another.
Criteria
When modeling forces, we represent a force with a greater magnitude by using_____.
Longer arrows
When two objects interact (push or pull on each other) the force pairs are always______.
Equal and Opposite
The observations or measurements made and collected during a scientific investigation.
Data
The process of studying and/or organizing data; this may include creating tables, charts, or graphs that can be used to identify patterns or trends in the data.
Analysis
Variable/condition that is purposely changed in the investigation
Independent Variable
The measured results of the investigation.
Dependent Variable
Are the forces balanced or unbalanced when the sum of all the forces on an object are equal and opposite.
balanced
Are the forces balanced or unbalanced when the sum of all the forces on an object are not equal and/or opposite.
unbalanced
What is a change in motion?
When an object changes its speed (speeds up, slows down), or direction (rebounds).
The name of material that is designed to cause the amount of force in a collision to act over a larger area, reducing the damaging effects of the collision forces on an object.
Cushioning
How a total force may be divided into multiple smaller forces.
Distribution of forces
